Flexible Hole Location Gages - Inch - 1"-8 - Inch
Flexible Hole Location Plugs are used for inspection of the location of a threaded hole in a part. Flexible hole location plug gages also referred to as centerline hole location plugs are used to determine the true centerline to centerline distances of threaded holes. The flexible hole location 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. Flexible hole location gages are 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 manufactures special plug and ring gages including oversize pre-plates, miniature thread gages, multiple starts, special leads, acme threads, buttress threads, square threads, extra length thread gages, and blue print specials.
