About Thread Gages

Thread gages are dimensional instruments for measuring and/or verifying thread size, pitch or other parameters. A variety of thread gaging instruments and tools exist such as measuring wire, tri-roll comparators, thread plug gages, thread ring gages and thread micrometers. The appropriate variable or fixed limit gage for an application should be selected based on internal and external thread type, specific thread designation (UNS, UNF, UNC, NPT, ACME, Buttress), part tolerances and gaging frequency (shop vs. high volume production).

Air Gages

Air gages use pneumatic pressure and flow to measure or sort dimensional attributes.

Dimensional Gages and Instruments

Dimensional gages and instruments provide quantitative measurements of product or component dimensional and form attributes such as wall thickness, depth, height, length, inner diameter (ID), outer diameter (OD), taper or bore.

Height Gages

Height gages are used for measuring the height of components or product features.

Laser Micrometers

Laser micrometers measure extremely small distances using laser technology.

Masters and Setting Gages

Masters and setting gages provide dimensional standards for calibrating other gages.

Plug and Pin Gages

Plug and pin gauges are used to compare hole and slot dimensions or locations to specific tolerances. This product area includes go gauges and no-go gauges.

Ring Gages

Ring gages are used for go / no-go assessment compared to the specified dimensional tolerances or attributes of pins, shafts, or threaded studs.
