Using Thread Gages
Using the principles of GO/NOGO gaging for internal threaded parts, a GO thread plug gage checks the minimum major diameter and minimum pitch diameter, and a NOGO thread plug gage checks that the maximum pitch diameter is not exceeded. The GO gage should thread into the part and the NOGO gage should not.
