JBO Thread Ring Gauge (NoGo) - UNF - Right Hand - 3A - 1 3/8 x 12 Endmill25 0 for smooth fillets andThe JBO Thread Ring Gauge (NoGo) is a precision tool used to inspect external UNF threads. Specifically designed for righthand threads in the 1 3 8 x 12 size with a 3A class fit, it helps ensure components meet Unified thread standards across manufacturing, automotive, and aerospace applications. This NoGo ring gauge makes it easy to verify that threads are within tolerance and quickly identify nonconforming parts, reducing rework and inaccurate
