Used to check the outside major diameter and pitch diameter limits on threaded parts
Like many other thread gages, these gages use a GO and NO GO method to determine if the threads fall within the tolerance or the class of fit. Thread ring gages are quite simple to use; if the GO end screws on, and the NO GO end will not screw on past three complete turns, then the part is within tolerance
Thread Ring gages are available in Straight Pipe and Taper pipe styles
What Thread Ring Checks:
GO gage checks the maximum minor diameter and the maximum pitch diameter size in a part
NO-GO gage checks for the hole not to exceed the minimum pitch diameter size on a part
