Flexible Hole Location Plug is used for inspection of the location of a threaded hole in a part. These gages are also referred to as centerline hole location plugs and are used to determine the true centerline to centerline distances of threaded holes. The flex plug gage is slotted at 90° increments to insure positive location on the thread flanks regardless of hole size. This feature provides a firm locating grip without pulling the shoulder of the plug up against the hole face and avoids any squareness error being transferred to the centerline measurement.

The center is concentric to the threaded section within .0002” TIR for probe location of coordinate measuring machines and also for plate inspection setups as “overpin” measurements. The flexible hole location plug gage can also be used with vee blocks to check concentricity to other diameters. Available in unified and metric sizes. Sizes #10 and smaller or M5 and smaller are of solid construction, with front taper to cover the entire product tolerance.

WESTport Gage provides a Certificate of Accuracy, traceable to NIST (National Institute of Standards and Technology), free of charge with every gage
