JBO Thread Ring Gauge (NoGo) - Metric Fine - Right Hand - 6g - M18 x 1.25 Face Mill Arbors repeatable hole sizes and cleanThe JBO Thread Ring Gauge (NoGo) is a precision inspection tool designed for metric fine threads. Specifically, it targets M18 x 1. 25 right hand threads, providing a reliable NoGo check to quickly identify components that are out of tolerance and should be rejected or reworked. Built for use in quality control, machining, and assembly environments, this gauge helps your team confirm that external threads meet exact size requirements with confidence.
