JBO Thread Ring Gauge (NoGo) - Metric Fine - Right Hand - 4h - M12 x 1 G repeatable bore dimensions with aThe JBO Thread Ring Gauge (NoGo) is a precision tool designed to verify external metric threads. Specifically configured for metric fine threads with a right hand orientation, it helps quality teams and machinists quickly confirm whether an M12 x 1 thread meets the specified size. With its NoGo designation, the gauge is used to identify threads that are out of tolerance, preventing undersized or oversized parts from progressing in production. Crafted
