The JBO Thread Ring Gauge (GO) - Metric Coarse is a precision go gauge designed to verify external metric coarse threads, specifically M9 x 1.25, with right-hand orientation and 6h tolerance. Built for engineers, quality teams, machinists, and inspectors, it delivers quick, reliable checks that parts meet spec and thread properly. The gauge features a knurled outer edge for a secure grip, enabling fast, one-handed inspections in busy workshops.

• Precise metric coarse GO gauge (M9 x 1.25, right-hand, 6h): Enables quick, repeatable go/no-go checks to confirm external thread size and fit, improving inspection speed and consistency.
• Hardened steel construction: Delivers exceptional durability and wear resistance for busy QC environments, helping maintain accuracy over time.
• Ergonomic, user-friendly design: Knurled grip and straightforward use support fast setup and reliable results across operators and shifts.

Designed to streamline quality control and precision engineering workflows, this gauge helps reduce downtime, lowers rework, and provides confidence that metric coarse threaded connections will perform as intended in mating assemblies.
