In the intricate world of manufacturing, precision is paramount. One tool that plays a critical role in ensuring this precision is the fixed limit gauge. This blog post will delve into the world of fixed limit gauges, explaining what they are, how they function, and their significance in part inspection. What is a Fixed Limit Gage? Fixed limit gauges, also known as fixed limit gages, are precision tools used in manufacturing to verify the dimensions and geometries of parts. Unlike other measuring devices, these gauges do not provide actual dimension values. Instead, their purpose is to ascertain whether a component falls within predetermined tolerance limits. The Philosophy Behind Fixed Limit Gaging The core idea of fixed limit gauging is not just to accept good parts but also to potentially reject parts that are near the extreme limits of tolerance. This strategy ensures that only components that meet strict quality standards pass the inspection. If a part is rejected by a fixed limit gauge, it can be re-measured using more accurate methods to determine its compliance with tolerance requirements. Types of Fixed Limit Gages There are primarily two types of fixed limit gauges: Double-End Gages: These gauges have a 'go' member on one end and a 'no-go' member on the other. The 'go' member should fit within or over an acceptable workpiece, while the 'no-go' member should not. Progressive Gages: These are not mentioned in the draft but are important in the context of fixed limit gauges. Progressive gauges combine the 'go' and 'no-go' members in a single unit, allowing for a quicker inspection process but with less distinction between the near-minimum and near-maximum part sizes. The Go/NoGo Concept in Plug Gages A crucial aspect of fixed limit gaging is the Go/NoGo principle, particularly in plug gauges. The Go plug, with a plus tolerance, is designed to gauge the smallest acceptable hole size. Conversely, the NoGo plug, with a negative tolerance, gauges the largest acceptable hole size. In practice, a Go gauge should pass through the hole, while a NoGo gauge should not. Why Fixed Limit Gages are Essential Fixed limit gauges are indispensable in manufacturing for several reasons: Quality Assurance: They ensure that parts meet the required specifications and tolerances. Efficiency: They provide a quick and effective method for checking parts, especially in high-volume production. Cost-Effectiveness: By identifying out-of-tolerance parts early in the production process, they help reduce waste and save costs. Standardization: They provide a consistent and standardized method for quality control across various manufacturing stages. FAQs Q: How do I choose the right fixed limit gage for my application? A: The choice depends on the specific dimensions and tolerances of the parts you are inspecting. Consider the material, size, and tolerance requirements of your components to select the most appropriate gauge. Q: Can fixed limit gages wear out? A: Yes, like all precision instruments, fixed limit gauges can wear out over time. Regular calibration and maintenance are essential to ensure their accuracy. Q: Are fixed limit gages suitable for all types of materials? A: While they are versatile, the material of the part can affect the choice of gauge. For instance, softer materials might require different gauging techniques compared to harder materials. Conclusion Fixed limit gages are a fundamental tool in the manufacturing industry, vital for ensuring the precision and quality of parts. Understanding their function, types, and application is crucial for any professional in the field of manufacturing and quality control. By adhering to the principles of fixed limit gauging, manufacturers can maintain high standards of quality, efficiency, and reliability in their products.

The taper is the angle and rate of change of the diameter, which affects the sealing performance of the thread. Gauges for Taper Pipe Threads Measuring taper pipe threads involves several gauges, each assessing different thread aspects: NPT L1 Thread Plug or Ring Gauge: This gage checks the thread form and the pitch diameter at the hand-tight engagement position, which is the theoretical point where the threads of the male and female parts first make contact. The L1 gage has a notch or a face that indicates the hand-tight position, which should be flush with the end of the thread within a tolerance of plus or minus one turn. The L1 gage is the primary gage for NPT threads, as it determines the basic acceptability of the thread. NPT L2 or L3 Thread Plug or Ring Gauge: This gage checks the thread form and the pitch diameter at the wrench-tight engagement position, which is the point where the threads of the male and female parts are fully engaged and sealed. The L2 or L3 gage has a different notch or face than the L1 gage, which indicates the wrench-tight position, which should be within a certain distance from the end of the thread. The L2 or L3 gage is optional for NPT threads, as it depends on the application and the design of the parts. NPT Taper Gauge: This gage checks the taper of the thread, which should match the NPT standard of 1 in 16. The taper gage is a plain plug or ring gage that has a series of steps or grooves that correspond to different diameters along the length of the thread. The taper gage is used in conjunction with the L1 gage, which acts as a guide to determine the gaging position. The taper gage should fit snugly into the thread without being forced or loose. Measurement Best Practices Effective use of these gauges involves following proper procedures, applying the correct force and torque, and ensuring regular calibration. The ASME B1.20.1 specification provides detailed guidelines on using these gauges. Advanced Considerations in Taper Pipe Thread Measurement   Material Impact on Measurement The material of the pipes can affect measurement accuracy.

It provides a closer tolerance and increased thread engagement, resulting in a more secure connection. 3G plug gauges are designed to check the internal threads of nuts or the external threads of bolts with a 3G class of fit. These gauges ensure a tighter fit and higher precision by measuring the accuracy and quality of the threads. 4G Class of Fit: The 4G class of fit is the tightest fit among the three classes. It offers the highest level of precision and thread engagement, ensuring a secure and reliable connection. 4G plug gauges are designed to check the internal threads of nuts or the external threads of bolts with a 4G class of fit. These gauges ensure the highest level of accuracy and quality by measuring the threads' dimensions.  It is important to note that Acme thread plug gauges come in different sizes and tolerance classes. The size of the gauge should match the thread size you are working with to ensure accurate measurement. The tolerance class refers to the acceptable range of variation in the thread's dimensions. Choosing the appropriate tolerance class ensures the proper fit and functionality of threaded components.  In conclusion, Acme thread plug gauges are essential for measuring the accuracy and quality of Acme threads. The three classes of fit - 2G, 3G, and 4G - provide different levels of tolerance and thread engagement. Whether it is a general-purpose fit, a tighter fit, or the highest level of precision, there are specific plug gauges designed for each class. Consider the class of fit, size, and adherence to relevant standards when selecting a plug gauge. By using the appropriate gauge, you can ensure the reliability and functionality of threaded components in power transmission and linear motion systems.

A thread plug gage is used to check the correctness of the pitch diameter of an internally threaded part, such as a nut. It is designed to inspect the functional thread and pitch diameter, and to check pitch diameter limits and the outside and inside major diameter on threaded parts. A thread plug gage is typically double-ended, with one end carrying the GO gauge and the other end carrying the NO-GO gauge. The GO gauge should pass through the entire length of the nut without requiring too much rotational force for acceptance of the part. The NO-GO gauge can enter into the nut at most over two turns and not beyond. On the other hand, a cylindrical plug gage is used to check whether a given dimension, such as a hole, is too large or small. It is used to check a drilled hole or the minor diameter of a threaded hole . Cylindrical plain plug gages may be used for gaging hole sizes to determine if the hole is within the upper and lower limits of the product tolerance. The hole size can be determined by using go and no go plug gauges. The go gage is used to verify the low limit. The no go gage is used to verify the upper limit. In summary, thread plug gages are used to inspect functional thread and pitch diameter on threaded parts, while cylindrical plug gages are used to check whether a given dimension, such as a hole, is too large or small.

Introduction Different applications require different types and varieties of tools to ensure the precision and accuracy of measurements. Hex gages are special tools that are used for the inspection of the wrench openings and spark plug wrench openings. Hex gages are essential if you want to measure or inspect machine head fasteners; moreover, they are used for ensuring that the hexagonal holes of parts or workpieces have been machined properly. More on Hex Gages Hex gages are manufactured from oil-hardened tools steel with HRC above 60. Also, Hex Gages, both GO and NOGO are manufactured to ANSI/ASME B107.17M specifications within metric sizes from .70mm to 75.00mm and fractional sizes from .028" to 3.00". Hex Gages inspect wrench openings for both, inch and metric sizes. The dimensional data covered in the stated standard includes data for; Spline socket cap screws Different types of hexagons Set screws Shoulder screws Hexagons, and Spline keys are recognized as American Standard All the aforementioned Hex gages are made with absolute precision and are ideal for measuring/inspecting machine head fasteners. You will find that majority of Hex Gages, if manufactured by quality manufacturers like WESTport Corporation, comes with a certification of accuracy and are also NIST traceable. WESTport Corporation also provides custom Hex Gages that are built as per the specifications of the customers. This includes gages with extra length, tighter tolerances, the use of alternative materials, and extensions. In particular, the WESTport Hex Gages are made with 60/62 HRC tool steel with long-form calibration services also available.  As for their application, they are used to gage hexagon sockets that are or aren’t chamfered as per the ANSI/ASME B107.17M or ASME B18.3. The gage has two sides or members, GO and NOGO sides. The GO side should be able to freely enter to the minimum key engagement depth that is specified in the standard. The NOGO side should not be able to enter the key engagement depth. Contrary to the rotary broaches, there is no taper on the Hex Gages. This is why they are held to tight tolerances. The gages are hand-held and inspected the following way:  If the GOgage goes inside the hole perfectly, then the workpiece passes inspection If the GOgage can not go inside the hole altogether, then the workpiece fails inspection If the NOGO gage goes inside the hole, then the workpiece fails inspection In the NOGOgage does not goes inside the hole, then the workpiece passes inspection Conclusion The WESTport team has been delivering precision quality gages worldwide since 1989. In putting the needs of our customers first, we are committed to continuously improving our products, processes and services to maintain our position as a global leader in our industry.

Introduction Cylindrical plug gages are available in a variety of designs predicated on size and use. The preceding is a breakdown of the many designs. The taperlock gage gets its name from the tapered shank that latches into the tapered aperture at the end of the lever. It is the American Gage Design Committee's time-honored standard for gages up to 12 inches in diameter. The truth that these gages have enough tolerance and size marked on the shaft of the sections is a benefit. There is no doubt as to what they've been if and when they are detached from the handles. The NoGo and Go members have a varied length of gauging surface, which aids in identification. Because the NoGo gage is not meant to enter the component, it is permitted to make it shorter. Read on to learn more about WESTport's Trilock Cylindrical Plug Gages. Trilock Cylindrical Plug Gages’ Progressive Design   In certain circumstances, having the NoGo and Go diameters on the same gage member might save some gauging time. For example, a progressive plug is appropriate for inspecting a short hole that is exposed on both sides. Furthermore, the opening cannot be subtler than the plug's Go portion. Progressive type gages are often taperlock, although any design may be made progressive. The gauging members are just basic pins that may be withdrawn from the handle by tightening the collet nuts on the ends. Marking the tolerance and size on the tips of larger gage members helps to identify them. When the gage is too tiny, it is impossible to discern between the Go and NoGo members without the use of measuring devices. The collet nuts at the handle's ends are colored differently - red for NoGo and green for Go. This traffic light method is frequently used in attribute measurement. Trilock Design The pin (reversible) and Taperlock systems are not suitable for big, heavy gages. The trilock configuration has been proven to be ideally adapted for gages with diameters ranging from 8 to 12 inches. The trilock mechanism superficially resembles the design. The grip has triple prongs on each end that slide into slots, distributed uniformly around the gage members' centre hole. A bolt secures the part to the handle, while the trilock prongs and grooves provide stability. Trilocks, like pin (reversible) locks, are bidirectional because either side may be fastened to the lever. Therefore, if the user values the reversibility characteristic, which allows for dual usage, one can buy reversible gages in all sizes in the range. Military specifications, which military contractors must normally follow, demand for pin type reversible gages in sizes ranging from .510 to 1.510 inches and taperlocks in sizes ranging from .510 to 1.510 inches. Trilocks are advised for sizes ranging from 1.510 to 8.010 inches. The paramount concern in creating a very big gage (more than an 8-inch diameter) to keep it lightweight, enough to carry effortlessly without tiring the operator out. Because these gages must be fully reliable in size and roundness, they are made with very little metal parts as feasible. For convenient handling, the annulus gage has twin screw-in ball grips similar to those seen on machineries.  Conclusion Since 1989, the WESTport team has been providing excellent quality Trilock Cylindrical Plug Gages all around the world. We are devoted to consistently improve our goods, processes, and services in order to preserve our reputation as a dominant force in our market by putting our customers' interests first.

Individual NoGo or Go gauge members, as well as assemblages with one or two gauge members with a handle, are supplied. The Purpose of Unified Miniature Screw Thread Gages A thread gauge is a measuring device used to measure the dimensions of a thread, such as the diameter, pitch, and angle. Internal threads are checked with plug gages, whereas exterior threads are checked with ring gages. Each gauge is divided into two sections: a GO gauge and a NO GO gauge. To verify the thread, both components should be utilised. The Thread Measuring System measures pitch diameter precisely and confirms that the thread plug gauge is well within range. The optimum thread plug gauging technique employs different pairs of thread plug gages. One or two gages can be utilized for in-process inspection, another for final inspection, and a primary thread plug gauge preserved for dispute if gages fail to correspond on approval or denial.

Introduction WESTport provides a complete line of cylindrical ring gages (steel and chrome) for go/no go gauging. The gages are perfect for evaluating manufactured items' outer diameters. A tester can swiftly pass or fail items using go/no go gages instead of obtaining time-consuming measurements from more costly testing instrument. Go ring gages are made with a negative tolerance. They are manufactured with a plus tolerance. The go gauge is used to confirm the upper limit. The no go gauge is used to ensure that the lower limit is met. Cylindrical gages, like fixed limit gages, are designed to fit the part's minimum and maximum material conditions. Generally, the fixed limit gauge is a three-dimensional duplicate of the mated part. This gauge tolerance mechanism assures that an examiner must never approve a faulty component. The use of fixed limit go/no go simple cylindrical gages needs just minimal training. The inspector merely needs to ensure that the gauge fits over the outer diameter of their component. Cylindrical Ring Gages -– Specifications Cylindrical ring gages, also known as plain ring gages, are used to verify the exterior dimensions of produced products. They may also be used to calibrate an instrument, whether electronic or air, and exist in a variety of sizes and styles. Ring gages with a diameter less than 1.510 are made without the need for a hinged external diameter, whereas gages with a diameter more than 1.510" are created with a hinged diameter. Removing excessive content from the external ring gauge diameter reduces the weight, making it simpler for the user to operate. Perfect for GO NOGO and master gauging. The NO GO ring is distinguished from the GO ring by a circular groove on its circumference. Air gages, bore gages, and internal micrometers can all be set using plain ring gages. Lead inaccuracies on readings can be reduced by utilizing the very same size master. Ring gauge blanks are stabilized by rotating these across high temperatures ranging from -130°F to +300°F. They are polished and lapped to guarantee optimal abrasion resistance and longer wearability. The gauge is next tested for class and size in a temperature-controlled lapping room before being finished in our environmentally controlled ISO 17025 metrology laboratory. ANSI/ASME B89.1.6 - 1984 ANSI/ASME B89.1.6 - 1984 Gage blanks fulfill all of B47.1-criteria. Ring. Available in sizes as small as 015" to 25".

British thread gauges are an essential tool used in many industries to measure the dimensions of screw threads. They come in a range of sizes and types, each designed to measure specific threads. In this article, we will explore the different types of British thread gauges and their uses. Whitworth Gauges Whitworth gauges are used to measure threads with a 55-degree angle, also known as Whitworth threads. These threads were commonly used in British engineering until the 1950s. Whitworth gauges come in a range of sizes, from 1/16 inch to 6 inches. British Standard Pipe (BSP) Gauges BSP gauges are used to measure threads on pipes and fittings. They come in two types: parallel and tapered. Parallel BSP threads have a constant diameter, while tapered BSP threads have a gradually decreasing diameter. BSP gauges come in a range of sizes, from 1/16 inch to 6 inches. British Association (BA) Gauges BA gauges are used to measure small threads commonly used in precision engineering. These threads have a 47.5-degree angle and come in sizes ranging from 0BA to 22BA. BA gauges are commonly used in the manufacture of clocks, watches, and other precision instruments. British Standard Fine (BSF) Gauges BSF gauges are used to measure fine threads with a 55-degree angle. They were commonly used in British engineering until the 1950s. BSF gauges come in a range of sizes, from 1/4 inch to 1 inch. British Standard Whitworth Fine (BSWF) Gauges BSWF gauges are used to measure fine threads with a 55-degree angle. They were commonly used in British engineering until the 1950s. BSWF gauges come in a range of sizes, from 1/4 inch to 1 inch. In conclusion, British thread gauges come in a range of types and sizes, each designed to measure specific threads. The type of gauge used will depend on the type of thread being measured and the industry in which it is being used. It is important to use the correct gauge for each application to ensure accurate measurements and reliable results. Additionally, it is important to keep thread gauges clean and properly maintained to ensure their accuracy over time. With the proper use and care, British thread gauges can provide accurate and reliable measurements for years to come.  Written by WESTport Corporation. All rights reserved.

Introduction An ANPT L-1 Ring Gage is a special gage that is used on the external rings of devices or components. This includes plugs, pipes, or other forms of fittings that have ring threads. But contrary to other gages, the ANPT L1 ring gage is applicable on ANPT threads which are also called the Aeronautical National Pipe Taper threads. ANPT threads are different in comparison to NPT threads as they do not require any form of sealants. Whereas NPT threads require sealants since they are not designed to be used in aeronautical applications. ANPT threads are suitable for aeronautical applications where there is a need for a sealant thread joint that is not possible with either O-rings, gaskets, or straight threads. How To Use It? All the external threads are first gaged with the L1 thread ring gage which travels L1 distance over the threads and engages the threads that will be engaged when the component is hand-tied. To check the threads beyond the L1 length, an L2 ring gage is used. In essence, ANPT thread ring gages are available in three measurements: The ANPT L1 ring gage also called the thin ring is used for checking the thread elements over the length of engagement that is hand tightened The ANPT L2 ring gage also called the thick ring, measures the thread elements when the component is tightened with a wrench The final is the ANPT 6-step plain ring which is used for checking the major and minor diameter of the male. Moreover, ANPT thread ring gages are measured on the SAE AS71051 standard. More On ANPT L-1 Ring Gage The process for measurement is rather simple. Simply place the ring onto the thread and rotate the gage. It should travel smoothly all the way up to the L1 distance, which are the thread elements that are engaged when the component is Hand tightened. The ANPT L1 screw threads have a larger major diameter in comparison to NPT gages. Similarly, the minor diameter is also larger, and the rings are designed such that they form a mechanical seal that eliminates the need for using any kind of sealant, making them ideal for aeronautical applications.  ANPT threads are measured in the same fashion as NPTF threads, both internally and externally (we use the ANPT L-1 ring for external measurement). But the gages are still dimensionally different which is why they cannot be used interchangeably. From the basic number of turns specified for the ANPT L-1 ring, a turn of 1 ½ from the basic turn is still acceptable for the L2 ring gage.

Introduction ANPT plug gages are used for gaging internal ANPT threads. The process involves screwing up the plug gage by hand into the internal thread of the pipe or product at hand. In comparison to other gages of the ANPT thread family, the ANPT L3 plug gage is used to check the threads that will be engaged once the product is tightened with a wrench for practical application. Besides the ANPT L3 plug gage, there are: ANPT L1 thread plug gage which is used to check the engagement of the thread elements when the product will be tightened by hand, and ANPT 6-step plain plug that is used for checking the minor diameter of the female fitting. More On ANPT L3 Plug Gage The process for gaging the internal thread of a product involves not just ANPT L3 plug gage, but all three gages mentioned above. First off, the thread is gaged with ANPT L3 plug gage, also called the limit-type L1 taper thread plug gage. The gaging notch that most nearly represents the size of the thread is noted. Although the ANPT threads are similar to NPT threads, the difference in the application for aeronautical purposes dictates that they must be controlled very carefully for taper, thread form, and diameter. This is because up until the length of 2-inch size, the ANPT and NPT threads are almost identical and have a requirement of an L1 gage. From the primary L1 threads that are measured with the L1 gage, the threads thereafter are referred to as the “L3 length” which is measured by the ANPT L3 plug gage. These are the threads that will be engaged when the threads of the product are tightened with a wrench. ANPT L3 plug gage is also a limit type gage whose total length equals L1 + L3. But despite this, the gage only has four threads at the small end. This is why, for a thread to be accepted on the L3 gage, the position of the gaging notch must coincide with half turn of the position previously noted on the L1 gage. The ANPT threads have a distinctive design to make a true seal that eliminates the need for a sealant. They make a true seal by crushing in on themselves. The ANPT L1 and ANPT L3 threads are needed for measurements of the female threads. Together, L1 and ANPT L3 plug gages measure the:  Lead Taper Pitch diameter, and Major diameter For measuring the minor diameter of the internal thread, the amount of the truncation is noted. Since the pitch diameter and truncation vary with limits, the minor diameter will also. The three-pitch diameter gaging positions are: Basic Minimum Maximum These pitch diameters necessitate 3 pairs of maximum and minimum truncation steps that amount to a total of 6 positions.

Introduction ANPT L2 ring gage is the second ring gage that is used for the measurement of the external rings on components like fittings, pipes, plugs, etc. Before this, ANPT L1 ring gage is used which is for the purpose of determining the thread elements that are engaged when the component is Hand tightened. In contrast to that, the ANPT L2 ring gage is used to engage the thread elements that will be engaged when the component is wrench tightened How To Use It? ANPT L2 ring gages are used in conjunction with L1 rings as well as with the 6-step ring. However, L1 and 6 step rings are more commonly used in conjunction in contrast to ANPT L2 ring gage. The L2 gage measures the effective external threads that are situated beyond the L1 distance. The application of both, L1 and L2 gages are similar to a major degree with a difference in the count of the number of turns that the product travels or fails to travel, in case the piping of the component is determined to be faulty. More On ANPT L-2 Ring Gage ANPT or the Aeronautical National Piper Thread rings are different from the NPT or the NPTF thread rings, given that they are for aeronautical applications. The do not require the use of any sealants as the threads form an airtight mechanical seal that prevents any sort of leakage. This is why they are called “dry seal” threads. Although the ANPT threads are similar to NPT threads, the difference in the application for aeronautical purposes dictates that they must be controlled very carefully for taper, thread form, and diameter. This is because up until the length of 2-inch size, the ANPT and NPT threads are almost identical and have a requirement of an L1 gage. The ANPT L2 ring gage is for measuring the second half of the threads that are engaged when the component is wrench tightened After both, the L1 and L2 lengths have been checked, the ANPT 6-step ring is used which helps to measure the major and minor diameter of the threads of the part in use. ANPT threads are measured in the same fashion as NPTF threads, both internally and externally (we use the ANPT L-1 ring for external measurement). But the gages are still dimensionally different which is why they cannot be used interchangeably. From the basic number of turns specified for the ANPT L-2 ring, a turn of 1 ½ from the basic turn is still acceptable for the L2 ring gage.  Conclusion WESTport Taper pipe ANPT L2 Ring Gage is available in a variety of styles and over a wide range of measurements. WESTport stands proud as an ISO 17025  manufacturer of quality assurance products with a commitment to client satisfaction and the provision of reliable products as an industry leader. Production units with regular and excessive use of Taper Pipe NPTF L3 Plug Gage are advised to have several spares at hand along with a master thread plug to regularly check on the wear and tear of their ANPT L2 Plug Gage.

Introduction: ANPT or “Aeronautical National Pipe Taper” Plug Gages are devised for their use on aeronautical components such as plugs, pipes, and other similar fittings that need a thread joint that is sealed mechanically. For these applications, gaskets, O-rings, or straight threads are not applicable. ANPT 6-Step Plug Gage is also used in the same application with its application being different from that of NFTP and NTP plug gages. The Use of ANPT 6-Step Plug Gage: The ANPT 6-Step Plug Gage is used for the truncation check of the three-pitch diameter conditions where the plug has a minimum and a maximum truncation step of the pitch diameter conditions. The three conditions include: Minimum Basic, and Maximum To check truncation, ANPT L1 plug is used in conjunction with ANPT 6-Step Plug Gage. If the face of the product in check lies between the basic minimum and basic maximum steps of the truncation plug, then the L1 plug indicates that the product belongs to the basic pitch diameter. If the said product falls between the MN and MNT steps, indicates that that product diameter is in the minimum range. Finally, if the product falls between MX and MXT steps, this indicates that the pitch diameter is maximum. The three gaging notches of ANPT 6-Step Plug Gage represent tolerance of +/- one turn. The L1 gage is used as a guide that helps in determining the gaging position. The requirements for ANPT 6-Step Plug Gage are spelled out in ANSI SAE AS71051. The ANPT screw threads are designed to have no interface between the crest and the root of the threaded assembly when they are screwed with NPT threads. However, when screwed with NPTF threads, the ANPT thread will have an interference fit between the root and the crest. The fit will either be on the minor or major diameter of the screw thread. This is dependent on the fact which part is NPTF. Finally, to form a seal, sealant will be required because there will be no mechanical seal formed. Also, it is worth noticing that before the 2-and-a-half-inch marker, the wrenching length of NPT threads and ANTP threads is the same.

Introduction: ANPT L-1 Plug Gage is used to check the internal thread rings of the aeronautical equipment such as pipes, fittings, plugs, etc. ANPT or Aeronautical National Form Pipe Taper Thread Plug Gages are used in applications where gasket, straight threads, or O-rings are not applicable; particularly in aeronautical applications. More About ANPT L-1 Plug Gage: ANPT L-1 Plug Gage is used to first gauge the internal threads. The gaging notch that most accurately represents the size of the thread is hence taken a note of. It is used to check the major diameter, pitch diameter, lead, and taper. The major diameter is only measured to the upper threads which are hand-tied. The later threads, which are measured by ANPT L-3 Plug Gage are measured for wrench tight position. The parts checked with ANPT L-1 Plug Gage are considered acceptable when they come flush with the notch. This means they will come close to either plus one or minus one turn and check the first four screw threads. Similar to NPTF, ANPT threads also employ an L1 and an L3 gage to measure the first four and the last three thread rings. Likewise, they both require plain taper 6-Step Crest-Check pipe plug gauges. The L-1 gage, more particularly, the ANPT L-1 Plug Gage is first used to gauge the size of the hole in contrast to the screw thread tolerance which could be either basic, minimum, or maximum. Albeit the ANPT internal pipe threads are practically the same as the pipe threads of NPT, they have a distinct application for their use in aeronautical applications which is why their diameter, taper, and thread form are very carefully controlled to form a seal that doesn’t need application of external sealants. These sealed threaded joints are also needed in applications where O-rings, gaskets, or straight threads won’t get the job done. Similar to ANPT L1 plug gage which checks the external diameter, the ANPT ring gages are used for checking the external diameter of pipes and ends with rings. The plug has a distinct difference from the basic NPT plug where in addition to its basic steps, we have the maximum and minimum steps that are used for measurement as follows: The product is in tolerance if its face is between the maximum and minimum steps of the plug. To check the depth beyond L1 depth which is measured with ANPT L1 plug gage, the ANPT L3 plug gage is used. Furthermore, the truncation is checked with a six-step plain taper plug gage which includes maximum and minimum truncation steps for each of the three-pitch diameter conditions which are maximum, minimum, and basic. It is also noteworthy that there should be no shake or wobble during the measurement. This is an indicator of taper error and must be tended to on an immediate basis. Conclusion: At WESTport Corporation, we have been providing the industry worldwide with precision measuring instruments and calibration services since 1989. WESTport employs state-of-the-art measures to ensure all our products comply with the ISO 9001, and ISO/IEC 17025 standards. Moreover, our expanded product line includes thread and plain gages, API Plug and Ring Gages, taps and dies, medical gages, spline gages, and full-service metrology laboratories for tool calibration, repair, and onsite services.

Introduction ANPT or Aeronautical National Pipe Taper is a form of ring threads that are used in components like plugs, pipes, fittings, etc. The ring is particularly dedicated for aeronautical applications where equipment needs a sealing thread joint. In the stated application, O-rings or gaskets and even straight threads are not applicable.  When these rings or threads are located outside a component, we use ANPT 6-Step Ring Gage to measure the pitch diameter size of the part in question. This is essential for all dry seal or aeronautical components. The ANPT 6-Step Ring Gage is used in conjunction with the ANPT L1-ring gage. How Is It Used? The use of ANPT 6-step ring gage is similar to that of ANPT 6-step plug gage, just on the outside. In other words, the gage is used to check the major diameter of the male fittings and in conjunction with that, the L1 ring is used to check the thread elements that may travel across the distance that is engaged when tightened by hand.  The ANPT 6-step ring gage is used to check the maximum and minimum truncation steps. On the ring, there are maximum and minimum truncation steps for each of the three conditions of the pitch diameter. Minimum, Basic, and Maximum. The part must fall between the B and BT steps on the ANPT 6-step ring gage if the LI ring shows it to be of the basic pitch diameter. Whereas, if the part falls between the M and/or MNT steps, it means that the L1 ring should show the pitch diameter to be of minimum diameter. Finally, if the part falls between MX and MXT steps, it means that the pitch diameter of the part as measured by the L1 gage should be of maximum diameter. It is also vital that there should be no permissible wobbling or shaking otherwise the part may not be suitable for the application intended. Especially the truncation of lead, angles, and roots must be checked on the tool wear at every time possible by projection. More On ANPT 6-Step Ring Gage The application of thread ring gage is very easy, but it is still recommended to consult with the diagrams and datasheet first. It falls upon the user as a responsibility to ensure that the ring gage correctly engages all the special pitch diameters along with the major and/or minor diameters, pitches/TPI, and the class of fit. Moreover, it must also be confirmed if the gage conforms to the proper standard of the national/international standard. Moreover, it is suggested to take care of your ANPT 6-step ring gage after every use to ensure the longevity of the product life. Ensure recalibration is conducted periodically and the gage is cleaned after each use. Keep an eye out for any chips, grits, or burrs that may cause unnecessary scratches and wear to the major/minor diameters of the thread gage along with its gage flanks. Conclusion ANPT 6-step ring gage from WESTport Corporation is ideal for measuring the external threads of pipes and/or other equipment and ensuring the said equipment or part in question falls within the said parameters. At WESTport corporation, we are at the forefront of presenting the industry’s highest quality and most affordable line of measuring equipment and tools.

Introduction:NPTF L1 ring gages inspect the hand-tight engagement or the functional size of a part in question. This includes the male threads or the nipple that must conform to specific calculations before being deemed usable. NPTF L-1 RIngs are designed to conform to the ANSI/ASME B1.20.5 standards. Gaging the NPTF external threads requires using more equipment so it confirms the standards stated. Screw thread pipe ring gages have two basic classes which includes plain and threaded. NPTF Rings L-1 belongs to the latter. The gage is threaded onto the pipe or equipment to be measured via hand. More About NPTF Rings L-1:NPTF is also called “Dryseal” because the thread tolerance is controlled very strictly. Still, the gages are used in a similar manner to plug gages except for the difference in the thread, which is internal in the case of pipe plugs and external in the case of rings. NPTF Rings L-1 is also called “thin” gage and parts that are measured on it are considered tolerable when they come flush to the ring’s end to a positive or negative one turn of the unmarked side, effective measuring the first 4 or 5 threads. For the further threads, NPTF L-2 ring gage is used which measures from the fifth to seventh threads. About NPTF Threads:NPTF threads are measured in the same fashion as ANTP threads both internally and externally (we use the NPTF L-1 ring for external measurement). But the gages are still dimensionally different which is why they cannot be used interchangeably. From the basic number of turns specified for the NPTF L-1 Ring, a turn of 1 ½ from the basic turn is still acceptable for the L2 ring gage. Both NPT and NPTF have the same taper per inch, as well as threads per inch, the real difference lies in diameters (major and minor) along with the crest and the root of the threads. The threads of both, NPT and NPTF are designed differently, with the NPTF threads being designed to have a smaller range than NPT threads and interfere with the mating thread. This in turn creates a dry mechanical seal that prevents leakage without the use of a sealant. This happens because the NPTF threads are designed to have interference at the root and crest of the threads not just minor, but also on the major diameter. This results in a leak-proof connection.Conclusion:NPTF L-1 Ring Gages from WESTport Corporation are ideal for measuring the external threads of pipes and/or other equipment and ensuring the said equipment or part in question falls within the said parameters. Using state-of-the-art technology and excellent customer service, we are thoroughly committed to ensuring we retain our status as one of the major quality assurance products and services.

Introduction:NPTF L-2 Ring Rages are used in conjunction with NPTF L-1 Rings, where it is used to inspect the wrench engagement threads of a coupling and the taper of the external threads. They are manufactured as per the ANSI/ASME B1.20.5 standard. WESTport provides a free certfificate traceable to NIST with each ring gage. L2 rings are also called the thick ring and that is used to check the thread element of those threads that have been engaged when tightened with a wrench. They are used in conjunction with the NPFT L1 gages and ensure dimensional compliance of the rings of the equipment or part in question. How They Are Used:The NPTF L-2 Rings are used as a check on taper where its engagement in the L-1 and L-2 dryseal must be within “One and a half” turn of the difference between the basic turn engagement of the ring gages. Basically, you are using the NPTF external ring gages in a similar fashion to pipe plug gages. The only difference is the measurement of the external gage instead of the internal. NPTF L-2 Rings are not just for the second half, but also the required half for the measurement of the fifth, sixth, and seventh threads. The L2 in the name is a representation of the dimension in the thread specification that coincides with the “Wrench Tight Engagement Length”.After the use of NPTF L-2 Ring Gage, a final check involves the use of a plain tapered ring gage, which is also called the NPTF 6 Step which helps in the measurement of the major diameter of the external thread of the part in question. More on NPTF 6 Step Rings:NPTF, along with ANPT (Aeronautical National Pipe Taper) external threads are first graded with NPTF L-1 Ring Gage for the measurement of the first five rings. The gage is hand tightened and the parts being checked are considered acceptable when they come flush to the end of the ring to plus or minus one turn of the unmarked side. The L-1 ring is also called the thin ring which is followed by the thick or the L-2 ring for checking the approximation of the rings or threads from fifth to seventh. With special emphasis on thread tolerance, the 6-step ring is used in the end.Similar to the L1 ring, the L2 ring is also used as per the count of the number of turns that determine the distance traveled by the ring over the object in question. L-1 and NPTF L-2 Rings together inspect the lead, taper, pitch and minor diameter. The face of the rings should not vary more than ½ turn to the relative position of the small end of the pipe and the basic gaging with the use of both L-1 and NPTF L-2. Conclusion:At WESTport Corporation, we have been providing industry world-wide with precision measuring instruments and calibration services since 1989. WESTport employs state-of-the-art measures to ensure all our products comply with the ISO 9001, and ISO/IEC 17025 standards.

Introduction:NPTF 6 Step Ring Gages are used in conjunction with an L1 gage to measure the pitch diameter of a part. The part in question may belong to aeronautical or dry seal parts depending upon its use and application. The use of NPTF 6 Step Rings ensure confirmation of the requirements of the Dryseal while it, itself conforms to the ANSI B22 Standards.More on NPTF 6 Step Rings:As the name states, each NPTF 6 Step Ring Gage is divided into 6 different steps which include: B BT MNT MN MXT MX The crest of the NPTF Ring 6 Step is used for inspecting the truncation limits and the taper of the major diameter. The steps or notches aforementioned are in relation to the position where the L1 gage is measured (may also include L3 or L2). If a part falls in the minimum range, it must measure between MN and MNT, similarly, if it falls between the basic range, it must measure between the B and BT range. Finally, if it falls in the maximum range, then it must fall between MX and MXT. Besides NPTF, it is also used to measure ANPT for the root-check gage of the threads of the products in measurement. How To Use:The three steps (B, MN, MNT) represent the minimum truncation for the basic minimum and maximum thread sizes whereas the other three (BT, MX, and MXT) represent the corresponding maximum truncation. They are used in a fashion similar to the 6 step plain plug, with the only difference being that the ring is always used with an L1 ring gage where the ring is used to confirm whether the thread crest is within the defined specifications.Difference Between NPT and NPTF:It is still noteworthy that there is a major difference between the thread design of NPT and NPTF, which is why they both have different requirements spelled out in separate ANSI codes. For National Pipe Taper or NPT threads, their requirements are expressed in ANSI B1.20.1 whereas, for National Pipe Taper Fuel or NPTF, the requirements are expressed in B1.20.3.What sets both NPT and NPTF apart is the root and crest of their threads along with their major/minor diameters. Besides that, you will find that both NPT and NPTF have the same pitch diameters, taper-per-inch, and even threads-per-inch. So it seems that the NPTF crest lies right where the parameter requirements of NPT lie, with the only difference being a minor range of thread crest. This is why NPTF requires more assembly and consideration in comparison to NPT. Moreover, the thread roots are also different. They create a mechanical seal when they are tied with the crest of NPTF mating thread at the assembly by deforming, hence earning them the name, dryseal. NPTF 6 Step Rings ensure closer control and confirmation of the necessary standards to form a satisfactory dry seal. Their essential application is to confirm the three zones of the gage overlapping. Conclusion:At WESTport, we provide you with quality that you can trust. We are manufacturers who are ISO 6506, ISO 9001 and ISO/IEC 17025 accredited which means each of our products complies with the strictest industrial standards.

IntroductionTaper pipe NPT L1 Ring gage essentially inspects the hand tight engagement or the functional size of male threads, pipes, or nipples. They have a tolerance of +/- one turn from the small end face of the ring. All NPT gages are made to ANSI/ASME B1.20.1 standards. It is used for measuring the external taper threads where it is screwed onto the threads of the product in question by hand. The thread is considered within the permissible tolerance when the working rings gaging face is at either + or – one turns from being flushed. More About Taper Pipe NPT L1 Ring GageTaper Pipe NPT L1 Ring Gage comes in two basic styles of screw; Plain Taper and Threaded Taper. We only require the L1 ring gage for the measurement of NPT threaded parts. When it is used, the ring is screwed onto the part from the side of the ring that is marked. It is also called thin ring gage as it only checks the first four to five threads. The L1 also specifies the Hand Tight Engagement Length which refers to the dimension in the thread specification. The Taper Pipe NPT L1 Ring Gage is meant to be used for general-purpose applications or pipe threads that are to be sealed with sealants or Teflon tape. Furthermore, NPT Threads do not require L2 or L3 checks. They are made in accordance with ANSI/ASME B1.20.1 standard. Taper pipe NPT L1 Ring gage is available in two types similar to the L1 plug gage; Go and No-Go thread ring gages. By means of application, they are very easy to use and are meant to be used by hand. In comparison to L1, the tolerance of NPTF thread is much more closely monitored. However, the purpose of the gages for both the standards remains the same. It ensures correct major diameter class of fit and TPI/Pitch along with special pitch diameters. At WESTport, we ensure that each threaded ring gage is designed as per the AGD (American Gage Design). Each ring undergoes stringent inspection to ensure it has been precision hand lapped to provide optimum finish and superior accuracy. The final inspection of each Taper Pipe NPT L1 Ring Gage is completed in an environmentally controlled ISO 17025 laboratory. PrecautionsIt is worth noticing that despite being manufactured with the highest standards, the Taper pipe NPT L1 Ring gage is still a precision tool which is why it needs the utmost care similar to any other tool of such nature. It is used by technicians, engineers, machinists, and Quality Assurance inspectors to ensure a part is made as per defined criteria. Given that it is a hand-operated tool, it is vital that it must be used with caution and diligence. WESTport Taper pipe NPT L1 Ring gage is an effective and easy-to-use tool that has markings for easy identification and is available in a variety of metric sizes. It is a highly accurate and a reliable tool that ensures fast and easy testing. ConclusionWESTport Taper pipe NPT L1 Ring gages comes with a Free NIST certificate of accuracy.

Introduction Taper pipe NPTF 6 step plug gage is used in conjunction with L1 plug to inspect the profile of the internal threads or crest truncation. In other words, its purpose is to measure the pitch diameter size of the essential components of the dry seal. It ensures conformance to dry seal requirements because to get an accurate measurement, it is vital to determine the distance from the L1 gage to the part. More About Taper Pipe NPTF 6 Step Plug Gage The 6-steps plug gage is used for testing the root or crest of the product thread in question. Since the three zones of the gage are overlapping, we need six steps for measurement. These six steps are as follows: MX MXT B BT MN MNT How Does It Work? If the result of the L1 gage indicates that a part falls in the minimum range, then it must fall between B and BT on the Taper pipe NPTF 6 step plug gage. If the part lies in the basic range, then it must fall between B and BT on the Taper pipe NPTF 6 step plug gage. Finally, if a part lies in the maximum range, it must fall between MX and MXT on the Taper pipe NPTF 6 step plug gage. Taper pipe NPTF 6 step plug gage is required by the NPTF class 2 threads. It is also known by another name which is Crest-and-Root Truncation Gage. Taper pipe NPTF 6 step plug gage is not threaded, rather, it has six steps grounded into it. The tool is used by inserting it into the hole and then reading the pairs which tell us the high and low limits of the three aforementioned conditions. This extra check is required by the class 2 threads. These gages are designed to the specifications of the Bureau of Standards Handbook H-28 and ANSI Standards B1.20.3 and comply with MIL-P-7105 Military Standards. Conclusion Taper pipe NPTF 6 step plug gage is essential for the measurement of the Crest-and-Root Truncation. Having no threads of its own, it has 6 steps that help in the identification of the thread in either minimum, basic, or maximum condition. They help us in gaging the internal diameter of holes that have been drilled into parts or machines. They are an essential tool for every quality control agent, engineer, machinist, or inspector to get an idea of the characteristics of the part in question. These measuring methodologies are essential and prevent the employment of difficult methodologies for measurement that may be more time consuming or simply not implementable for everyone. Based on that, a part is either accepted or rejected. At WESTport we offer a wide range of the highest quality precision tools, taps and dies, gages, and full-service ISO 17025 metrology laboratories for tool calibration, repair and onsite services. We are continuously improving our services and products to maintain our position as a global leader in our industry. Written by WESTport Corporation. All rights reserved.

Introduction Taper Pipe NPTF L3 Plug Gage is used for the inspection of the L-3 length of the engagement for taper and wrench tight. What makes NPTF gages different from NPT gages is that they are considered dry seal pipe threads. They are also called relationship gages which are used for inspecting the taper coupling and wrench engagement of the internal threads or couplings. Taper Pipe NPTF L3 Plug Gage is used in conjunction with NPTF L1 gages hence the name “relationship gage”. Use When internal threads are gaged, Taper Pipe NPTF L3 Plug Gage is one of the three main members used where the Taper Pipe NPTF L3 Plug Gage is used to checking the threads that will be engaged at the stage of wrench tightening. Since the gages are different in terms of dimension, it is vital that they must not be interchanged from one another. NPTF vs. NPT The primary difference is in the name, then there is a major difference of no sticking medium used like Teflon tape or pipe dope between the two threads in NPTF. NPTF gages are designed to bear a high critical crest tolerance which is why they are commonly inspected with a smooth 6 step plug or ring gage. The gage is used in conjunction with the NPT L1 gage that helps in establishing the tolerance of the product in question (whether the tolerance is min, nominal, or max.) The L3 in the name of Taper Pipe NPTF L3 Plug Gage refers to the need for a secondary inspection which may be required on the said threads for which the L3 plug is used. Do note that the plug is used for the inspection of the internal threads whereas ring gages are used for the inspection of external threads. Both L1 and L3 plugs are used on threads that are not plated. As such, it is imperative that the gage must not move 0.5 turns (+/-) from the position of the L1 gage. Gages that are plated have a different tolerance. Precautions It is vital that the Taper Pipe NPTF L3 Plug Gage must be treated with diligence as a precision tool as any type of mishandling or misuse, or forced use can cause unwanted deformities or nicks. This can compromise the integrity of the gage hence the measurements. Also, the gage must never be forced into a part that is under check. Moreover, keep the gage separate and never cram it with other tools as it may damage the threads of the gage. When you are done with the use of the tool, it is advised that you should oil or grease the tool to protect it from rust. Finally, if Taper Pipe NPTF L3 Plug Gage is to be shipped over long distances, store it in a separate container with insulation to prevent it from being damaged. Conclusion Taper Pipe NPTF L3 Plug Gage is a part of class 2 gages that are used specifically for measuring the crest and threads. The plugs themselves can only be checked with a master thread plug which is why it is advised to keep a spare. Production units with regular and excessive use of Taper Pipe NPTF L3 Plug Gage are advised to have several spares at hand along with a master thread plug to regularly check on wear and tear of their Taper Pipe NPTF L3 Plug Gage.

Introduction The Taper pipe NPTF L1 plug Gage, also called relationship gage are considered dry-seal pipe threads. Essentially, Taper pipe NPTF L1 plug Gage is used for the inspection of the pitch diameter of the hand tightened L1 length of any engagement. The NPTF part stands for “National Pipe Taper Fuel” where their requirements are spelled out in ANSI B1.20.3. NPTF vs. NPT Comparatively speaking, both, the Taper pipe NPTF L1 plug Gage and the NPT version will have identical taper-per-inch, threads-per-inch, and pitch diameter. What is different is their crest and roots of threads as well as their major and minor diameters. Though NPTF threads crest is well within the required parameters of NPT, they still have a smaller range in comparison. Where NPT threads are considered general-purpose pipe threads, NPTFs are reserved for more critical applications. In a sense, both are designed to screw together and that much is simple enough, but where NPT requires a “seal” to be truly leak-proof, NPTF doesn’t. Both NPT and NPTF standards are strikingly different in terms of threads as even the L1 gage requirements both have a difference of ½ in. size-wise. They are not interchangeable which is where the Taper pipe NPTF L1 plug Gage comes into play. The NPTF threads require more assembly for size check which is not possible with the NPF plug gage. Only a Taper pipe NPTF L1 plug Gage can check NPTF threads. More About Taper Pipe NPTF L1 Plug Gage Taper pipe NPTF L1 plug Gages are specifically designed for inspecting the functional thread and pitch diameter for the components with internal threads. The L1 indicates that Taper pipe NPTF L1 plug Gage belongs to class 1 thread gages for a functional check of taper deviations and continuation of thread beyond the L1 length of engagement. Being an L1 plug, the Taper pipe NPTF L1 plug Gage inspects the hand tight engagement of an internal thread or couplings as well as the functional size. At WESTport, all Taper pipe NPTF L1 plug Gages are manufactured as per ANSI/ASME B1.20.5 and come along with a Free NIST certificate of accuracy.

Introduction: Taper pipe NPT L1 Plug Gage is a piece of versatile measuring equipment that is used to check the integrity of the internal threads to ensure they meet the required standard precisely. As a type of measuring tool, they need to be sourced from reliable manufacturers to ensure the accuracy of measurement every single time. Also called Go No-Go Plug Gages (more on this later), the engagement with the internally threaded part must be done with delicate force. A Reliable Tool For Test: As a hand-operated tool, you need to ensure a smooth engagement or you risk damaging the threads. Standard industry practice is to give the Taper pipe NPT L1 Plug Gage three revolutions while inspecting the threads of an object. For instance, if you are measuring the threads of a nut, use the Taper pipe NPT L1 Plug Gage and give it three complete rotations. If the threads are clean, you will find that it goes all the way. If it becomes jammed or stops, stop turning immediately as the threads of the nut have obstructions and hence failed the test. Uses: Taper pipe NPT L1 Plug Gage is used by quality inspectors, manufacturing engineers, technicians, and machinists for the inspection of thread components and their precise calibration. They are an essential part of any quality control process to ensure the threaded components are made with the required calibration and are free of any obstruction. Types: Taper pipe NPT L1 Plug Gage are available in several types including: Go Plug Gages – A hand-held single-ended gage that has a handle and pin, which is very precisely machined for accurate verification of the dimensional tolerance of a threaded hole. Go Plug Gages are offered with No-Go Plug gages as they are both used in combination to determine whether a hole falls under the acceptable limits or not. It helps in the testing of the “minimum dimensional limit” of a threaded hole which is the representation of the “maximum amount of remaining material on the part under inspection”. If a Go Plug Gage fits into a hole, it is acceptable, if not, then the piece must be discarded. No Go-Plug Gage – It is used for the validation of the maximum dimensional limit of a threaded hole. This directly corresponds to the “minimum acceptable amount of remaining material” that should be on the part under inspection. If the No-Go Plug Gage doesn’t fit into the hole, it means that the hole diameter is “below” the acceptable limit. If it does fit, it means that the hole diameter is above the acceptable limit. The only acceptable condition is if Go Plug Gage fits and No-Go Plug Gage doesn’t fit. Go No-Go Plug Gage – This is a combination of both Go Plug Gages with one on each side. It speeds up the inspection process and simplifies its use. The sides are either labelled or color-coded for their identification but the visual difference is also quite obvious.

Threaded fasteners play a vital role in the construction of a wide range of products. Without accurate thread sizing, a fastener's ability to provide a secure connection is compromised. Manufacturers rely on thread gages to check fastener specifications and ensure the integrity of all threaded fasteners leaving their facility. Your thread gages are designed to be durable, but they may sustain some damage over time. If you know how thread gages can sustain damage, you will be equipped to identify faulty thread gages before they create serious problems in the future. 1. Abrasions One of the most common ways that a thread gage can sustain damage is through contact with the fasteners it is measuring. A fastener is either threaded through or into the thread gage. The threading process can create friction that causes abrasions to form on the interior surface of the thread gage. Abrasions have the potential to alter the profile of the thread gage, making it impossible to produce an accurate reading when using the damaged thread gage to take measurements. Be sure that you inspect your thread gages often for evidence of abrasions and replace damaged gages quickly to preserve the integrity of your fasteners. 2. Expansion Many of the thread gages used in modern manufacturing facilities are made from steel. Steel is a metal alloy that offers great strength and durability, but it does have a tendency to expand over time. The molecules within a steel product can start to relax once the steel is put into use. Environmental factors like temperature and humidity can influence the rate at which steel expands. You want to ensure that you are using your thread gages in a controlled environment. Fasteners should only be tested in temperature-controlled settings, and thread gages must be stored in a temperature-controlled space to prevent any damage caused by expansion. 3. Burrs The dimensions of a thread gage must be exact if you want to ensure that your fasteners meet strict design specifications. Anytime one metal product comes into contact with another, it's possible for burrs to form. Burrs are the result of contaminants that have cut their way into the surface of your thread gages. A burr can make it impossible to obtain an accurate measurement using your thread gage, and this could result in a decline in fastener quality. Inspect all thread gages used in your facility often to ensure burrs don't cause threaded fastener problems in the future. To learn more about thread gages or to replace your worn-out ones, contact a supplier.

Working inside an industrial facility, you come into contact with all types of machines and tools. You may work daily with milling machines, hydraulic cylinders, or laser-cutting machines. However, most, if not all, industrial facilities also use tiny components and tools for daily work, such as screws and gages. The gages you use to measure the individual "threads" on different screws are important; without them, it would take longer to get nuts, bolts, and screws to work together without problems. When dealing with them, think about these gage issues. Using Proper Type There may already be thread gages in your facility, even if you don't know one gage from another. Measuring screw threads with the incorrect type can produce inaccurate information. Ring gages are generally put to work when screw turn-per-inch details are required, while pitch diameter information is best determined by a plug gage. Familiarize yourself with the different types and learn how they're used so you can ensure your own results are correct. Monitoring Gage Condition Gages wear down like all the other machines and tools in your facility. Purchasing and keeping a so-called master plug can allow you to monitor and test gage conditions so that you can replace the objects when they're no longer calculating correctly. Watching for Corrosion Metal pieces like gages should always be protected against corrosion whenever possible. This means that you and others must remain vigilant about wiping down wet gages and venting the facility well so that humidity isn't a problem. You should also be wiping the gages periodically with oil-based wax. You may want to examine the market for gages that already have some anti-corrosive qualities so that you don't have to constantly concern yourself about rust. Stocking Extra Gages Your employees or co-workers are likely to need the same kinds of gages that you're using. Ensure that you have an accurate feel for how many gages of each type are being used on the floor every day and ensure that sharing isn't always necessary. This prevents work from slowing down and ensures no one is doing guesswork that could easily be eliminated with the right gage in hand. Training People Like yourself, many of your co-workers or employees may not be well-versed in gage practice and use. Hold short training sessions to introduce people to these tools and explain how they improve the work and output that happens in your facility. These tips should help your thread gages last, but you can ask a thread gage provider like WESTport any questions you have about them. 

Thread gages are important tools that are used in industrial settings to measure screw threads and calibrate gages properly. When your company invests in thread gages, it is natural to want them to last for as long as possible. While thread gages do not require a lot of maintenance, there are several things that should be done to keep them in good condition to ensure that they last a long time and can take accurate measurements and make the right calibrations. If you're ordering new thread gages, use the following tips to take care of them. Keep the Thread Gages Clean Keeping your company's thread gages clean can help extend their lifespan and ensure that they work properly as needed. Thread gages should never have extended contact with dirt and oil, as they can corrode the surface of the thread gage. This includes the oils on the skin, so make sure that anyone who uses a thread gage washes his or her hands beforehand. After calibration, the thread gage should be cleaned with a quality solvent that removes oil and dirt and then carefully wiped dry. Store in a Dry, Cool Area Since thread gages are used to make precise measurements, it is important that there are no changes to its size. Thus, it is important to keep thread gages stored in a cool, dry area where they will not be exposed to heat or sunlight since these things can cause the metal of the thread gage to expand and then contract when it cools down. It is best to store thread gages on a clean piece of cloth in a container and then place the container in a cool spot. Train Inspectors and Operators in How to Use and Care For Thread Gages When new thread gages are purchased for your company, it is a good idea to offer a refresher course in using and maintaining thread gages, so all inspectors and operators understand what to do. Proper training can help ensure that no thread gages are ruined due to improper use or not keeping the gages in the right condition. Keep Thread Gages Properly Labeled Since thread gages are available in different sizes, it is very important that each one is clearly labeled. If a thread gage is not labeled, it can be used for the wrong inspection or calibration, which can lead to the thread gage being damaged in the process. For more information, contact a company like WESTport.

If your industry relies on incredibly precise measurements and components that are assembled with mathematical certainty, it's important that you invest in tools that will allow you to achieve those goals. Purchasing a reliable set of thread plug gages is a great way to constantly verify that your components will fit together as designed, but the tools themselves could be at risk if you're not careful to use them properly. Below, you'll find a few suggestions that should help you maintain your thread plug gages for reliable and consistent usage. Following these tips is a great way to make sure that you receive accurate measurements every time and can put you in a position to generate reliable results that you know your customers will always be able to count on. Proper Force Application Finding the right balance of force when you use your thread plug gages may feel like a trial and error system, but it's an incredibly important task that you should be sure not to pass up. If you apply too much pressure, your gages could damage the threaded connection they're attempting to measure. On occasion, damage to the gages themselves may occur, leaving you struggling to determine if your readings are as accurate as you want them to be. Professionally constructed thread plug gages will be sure to fit snugly into a threaded hole without any force or cajoling necessary. One good way to make sure you don't accidentally end up misapplying force is to only have the gage available that is specifically designed to fit into a specific slot. This way, there's no risk of picking up and improperly sized tool and forcing it where it doesn't go, and you can be sure that your tools and your inventory will both remain strong and reliable. Full Length Measurements Some of the biggest stresses on the tips of your thread plug gages come in the insertion and removal process. If your attempts to expedite your checking process involve you using one gage many times in rapid succession, you may be more likely to cause structural damage to the gage and, simultaneously, receive inaccurate measurements. This method can also leave you vulnerable to manufacturing deficiencies which may appear further down a threaded shaft. Be sure to use your thread plug gages to measure the full length of a threaded surface if at all possible. Some connection points are designed to be shallow and thus won't be able to accept the full gage, and in those cases, it's important to follow the suggestions above about proper force. When available, however, using the full surface of your gage may be the best way to receive accurate readings. Utilizing Both Ends Both the "go" and "no go" ends of your thread plug gage fulfill a vital role in verifying the strength and usability of a given component. Putting too much repetitive stress on one end of the gage, as mentioned above, can put you in a position where it quickly wears down. Even with proper storage, you may find yourself with a damaged gage that suddenly risks the integrity of your operation. Rather than settling for substandard results, checking both threads and rings with both ends of your thread plug gage will help guarantee repeated results that allow for customer satisfaction in every component. Rather than processing returns and new runs, you can be confident that your manufacturing process will be successful the first time. The experts at WESTport Corporation will help guarantee you have access to the precise gage that will meet your manufacturing needs. Relying on our expertise is the first step in securing your manufacturing process for many years to come.

In contemporary times, we are surrounded by technology. Our entire world revolves around it, without which none of our work seems to be possible. Accuracy becomes the most important factor when it comes to using machines as the reliability of production totally depends on the advanced technology of the machines. For this purpose, it becomes indispensable to look for the specifications of the measuring tools used to check the precision and accuracy. Numerous precision measuring tools are used to ensure that the machines serve us with the correct data. These instruments need to be accurate enough on which one can rely on taking decisions and performing tasks. Due to this reason, calibration of measuring tools are done to assure that the measurements are appropriate and deliver correct information. What is Calibration? A process of juxtapositioning between a standard measurement and one which is used for measuring is termed as calibration. It configures an instrument, providing assurance that the result delivered is appropriate. When it comes to checking the precision of instrument through calibration, it should be 10 times the accuracy of the measuring device that is being compared with standard one. If there arises a case where measurements don’t meet expectation to that of the criteria, then with the help of calibration it is adjusted for achieving particular specifications. Why is Calibration Important? It serves us as a guarantee that tool which is used for the measurement is meticulous. For better understanding, we brought you few more reasons that would evidently explain its paramount value. No Manufacturing Errors, No Cost Sometimes, large manufacturing industries may face some flaws in the production. Consequently, the cost of it rises. Though defects would be small, their costs prove to be the high burden on the manufacturers. It would not only be expensive in the form of resources, but also as a waste of time. It can be avoided through calibration of measuring instrument that verifies if it delivers an appropriate result or not. Calibrating tools and gauges will evidently reduce the risk for attaining any possibility of production defects. But, ensure that the sensors which are used for its monitoring are appropriate in this process. However, laying hands on the correct calibrating tools would serve your purpose in the best way and it can be done by buying it from a trustworthy supplier such as Penn Tool Co. For gaining detailed information, you can explore penntoolco.com and get your desired products. Safety It goes without saying that when every functioning of the measuring instruments is verified under the process of calibration, it keeps all the processes safe. All the devices and machines which are used to produce products ensures its safety through this process.Certification Certification The accuracy of measuring device deteriorate with time fleets. And this wear and tear of the machine The accuracy of measuring device deteriorate with time fleets. And this wear and tear of the machine are occurred due to several factors affecting it. Therefore, it becomes imperative to look for the safety of it, which can be made possible by calibrating measuring tools proficiently. However, it can be said that certification of the machine is maintained through calibration. Now since you are introduced to the paramount importance of calibrating instruments, it is upon you whether or not to consider these points in your manufacturing process. Besides, it is for sure that this verification process won’t harm the production in any way.

Threaded holes and shafts can be found on many manufactured products in today's consumer market. In order for products to function properly, strict thread tolerances must be kept. Thread gages are commonly used to help measure the characteristics of a threaded hole or shaft. Two of the most common types of thread gages in use today are the go and no-go gages. These two gages can be used in tandem to help improve the quality of your threaded products. Go Thread Gage The primary purpose of the go thread gage is to measure the mating size of external threads. The go gage is screwed onto the threaded item to check the largest diameter of each individual thread. A go gage can also be used to determine if the unthreaded flank is long enough to ensure proper function. Using a go thread gage is simple. You simply screw the go gage onto the threaded item. If the thread tolerances are in line with your specifications, you will be able to screw the go gage up the full length of the threaded area by hand without using any significant force. If you are unable to complete the screwing process with relative ease, the threaded item doesn't meet parameters and must be discarded. No-Go Thread Gage No-go thread gages are used in much the same manner as their go gage counterparts. A no-go thread gage has fewer threads than a go gage. This reduction in threads is due to the fact that the no-go gage isn't designed to screw up the full length of a threaded item. Instead, the no-go gage shouldn't be able to complete more than a few rotations when used. This will ensure that the pitch diameter of the external threads on your threaded item do not fall below a set minimum. Keep in mind that force should not be used when you are measuring thread tolerances with a no-go gage. The use of force could cause serious damage to both your threaded product and your no-go gage. Access to thread gages makes it easier for manufacturing companies to determine if their threaded shafts and holes meet design specifications. Take the time to check your gages against a marked standard in order to ensure that your go and no-go thread gages remain accurate at all times. Extensive use can cause a thread gage to deteriorate, which compromises the accuracy of their results. For more information, contact a thread gage supplier.

If you're going to be using thread gages to analyze pitches on different things, such as screws, then you want to be careful with these instruments. You'll have a better time using them over the years if you know about these mistakes to avoid.  Not Washing Hands Properly Before Using Gage Thread gages may look really durable and most of them are, but they can become flawed if contaminants get on them. It's your role to keep this from happening and that starts with how you wash your hands. You need to put together a proper hand-washing protocol before any thread gage is picked up. This is the most effective way to keep contaminants — such as oil and dirt — from getting on the gages and preventing them from satisfying their intended role. Thorough hand-washing with strong chemicals can keep you out of trouble with this potential issue. Not Utilizing Maintenance Training Thread gages may seem like simple components, but they do have to be maintained in a lot of different ways. You don't want to forgo maintenance training just because you think you know how to care for them correctly. That could cause thread damage. You should utilize maintenance training with thread gages even if you feel like you know what care steps to perform. Then you can add to your existing knowledge and keep your thread gages better protected over the years. If you have workers that will be using thread gages, you want them using this maintenance training as well. Not Caring About Precision One of the most important factors of using any type of thread gage is precision. You need to have it in order to check fasteners or openings with threads correctly. If you don't care about precision and just let it fall by the wayside with your thread gages, then they won't do their job and you'll run into a bunch of future issues. Maintaining precision with your thread gages should always be a top priority and you can do this in a lot of ways. For example, cleaning and lubricating your thread gages will help them maintain their precision. Any time thread gages are relied upon, knowing how to care and use them will help you get the most out of these instruments. Part of this involves learning about pitfalls that can happen with thread gages, regardless of size and materials. Then you'll be fully prepared to maintain the amazing qualities that thread gages have.

The pitch is the distance between a fastener's threads. A gage aids in correctly identifying screws or bolts that will be used for fastening purposes and can prevent the purchase of materials that won't be the proper size for an application that is going to involve securing two or more materials together. Proper use and storage are essential in preventing inconsistencies in the manner in which a thread gage works. Clean And Dry A Gage A thread gage may possess an oblong shape, a series of holes, and printed markings. Thread gages are typically constructed of metal. The markings and the metal are susceptible to damage, especially if this type of tool is left in a moist area or is being stored near a work area that is going to require the use of heavy materials and sharp tools. If moisture is left on a gage's surface, corrosion may lead to the integrity of the metal being compromised. Dirty substances and gouges can alter the manner in which a measurement is taken, resulting in errors and difficulty with using a gage. Before and after each use of a gage, an end user should ensure that the tool is clean and dry. Gloves should be worn while cleaning the tool since the oils on the skin can affect the cleanliness of a gage. Prevent Rust And Store A Gage During the use of a gage, metal components should never be forced through the holes that run along a gage's surface. Upon completing a fastener analysis, a user should inspect both sides of a gage. A rust preventative material may have been applied to the tool when it was manufactured. A thin wax coating will eventually wear down, resulting in the need for another application of an anti-rust material. Rust inhibitors include sprays, gels, and waxes. A spray should be applied in a ventilated area. Both sides of a gage should be treated and plenty of drying time is needed. For a gel or a wax, an inhibitor can be brushed on or a gage can be dipped into the product. If a dipping method is used, a lint-free cloth should be used to remove excess gel or wax. Once the inhibitor has dried, a gage can be stored in the factory bag that the product came in or a plastic bag that seals. A gage should always be stored in a dark, dry area. For more information, contact a thread gage supplier.

There is a good chance that your company already uses some sort of quality control process to verify that your products are properly made and assembled before you send them off to your customers. However, although you might use other tools and equipment to perform quality control, and although you might think that your company does a good job with quality control overall, there might be some steps that you are missing. For example, using a thread gage during the quality control process is a good idea. If you aren't using one already, you should consider doing so for the reasons below and more. Make the Process Faster and Easier The employees who work in your company's quality control department probably work hard to ensure that the products are up to your company's standards. They might have a lot of responsibility since they might have to review and assess multiple different things while they are performing their checks. If you can make things a little bit easier for them, you probably want to do so. If employees are able to check fasteners quickly with a thread gage, this can simplify their jobs by just a little bit, which is something they are sure to appreciate. Thread gages can also help you speed up the quality control process since employees will be able to perform checks on fasteners a lot more quickly. Since speeding up the quality control process can help you get your products shipped out more quickly, this can make the use of thread gages worthwhile. Make Sure Products Are in Good Shape Thread gages make it possible for your employees to ensure that fasteners are secured as they should be in a more effective manner. This is a great way to verify that products are in good shape and ready to ship out. Plus, it makes it possible for employees to check for this without having to screw in fasteners by hand, as that can cause stripping and other issues. As you can see, if you manufacture and check products that have screws or other fasteners, but do not already use thread gages during the quality control process, then you might need to make this simple change. This should be a quality control step that is easy to implement, and it's something that can benefit your company for the reasons above and more. Contact a thread gage supplier for more information.
