The JBO Thread Ring Gauge (NoGo) – Metric Fine, Right Hand, 6h, M7 x 0.5 is a precision inspection tool for validating external thread diameters. Built for engineers, machinists, quality teams, and technicians, it provides a fast, repeatable NoGo limit to verify that parts meet the M7 x 0.5 thread size and the 6h tolerance class. Crafted from hardened steel, this gauge is designed to withstand daily use in busy workshops and QC labs.

• Hardened steel construction: Resists wear and maintains accurate dimensions under heavy use, delivering long service life in busy production environments.
• Metric fine NoGo gauge for M7 x 0.5: Enables quick, reliable external-thread checks with clear pass/fail guidance, helping you sort acceptable parts from non-conforming ones fast.
• Right-hand, 6h-toleranced design: Precisely matched to standard right-hand threads and the 6h class, supporting consistent measurements across parts and assemblies.

This gauge helps you streamline quality control by providing objective, repeatable measurements that support tight tolerances and reliable mating in assemblies. Its robust build reduces downtime, minimizes rework, and gives your team confidence that every threaded component aligns with specification.
