JBO Thread Ring Gauge (GO) - Metric Fine - Right Hand - 4h - M4 x 0.5 A&NF consistent surfaceThe JBO Thread Ring Gauge (GO) Metric Fine is a precision tool designed to verify the outer thread diameter of metric fine threaded components. It is ideal for engineers, machinists, quality inspectors, and workshop technicians who need fast, reliable go no go verification. Built as a GO gauge for right hand threads with M4 x 0. 5 pitch and 4h tolerance, it supports accurate assessment of components against standards. Crafted from hardened steel, it
