The lead gage inspects thread lead using contact points that seat in the threads of a part.

Thread lead is the distance between threads, measured on a plane parallel to the centerline of the threaded part.

The pitch of the thread determines the diameter of the contact points required for taking measurements.

Thread Lead Gages inspect both internal and external thread lead for a variety of thread forms and provide dimensional verification of product print data on the integrity of your threads.

Gagemaker has both two-point and three-point system lead gages that are designed to accurately inspect lead for ACME, Stub ACME, UN, and API threads.
