The JBO Thread Ring Gauge (GO) — Metric Fine, Right Hand, 6g, M48 x 3 — is a precision tool designed to quickly verify external thread diameters on metal components. It’s ideal for machinists, inspectors, and quality teams who need fast, reliable conformance checks for metric fine threads. With the GO designation, it confirms components that meet the specified major diameter and pitch for right-hand threads.

Crafted from hardened steel, this gauge delivers exceptional durability and wear resistance, maintaining accuracy even after extended use in demanding workshop environments. Its straightforward GO design makes it easy to identify properly conformed threads at a glance, supporting efficient quality control across production and repair tasks.
