China made 1.75-16UN-2A Thread Ring gauge with calibration reports, angle and pitch diameter and minor diameter are all in tolerance.

1.75-16UN-2A Thread Ring


A UN thread ring gage is a precision tool used to inspect the external threads of a fastener or component, specifically for Unified National (UN) threads. It ensures that the thread's pitch diameter and minor diameter are within specified acceptable limits. The gage consists of two parts: a GO gage and a NO GO (or NOGO) gage.

Individual GO and NOGO ring gage members are sold separately.
