The JBO Thread Ring Gauge (NoGo) is a precision tool for verifying external thread diameters on metric fine threads. Designed for engineers, machinists, inspectors, and quality teams, it helps you quickly confirm that M10 x 0.5 right-hand threads meet the 6h tolerance and are within spec. The NoGo function makes pass/fail decisions fast, supporting reliable quality control across assemblies and components.

Crafted from hardened steel, these gauges offer outstanding wear resistance and long-lasting accuracy even in busy workshop conditions. The user-friendly ring design supports fast, repeatable checks, so you can identify non-conforming parts at a glance and keep production moving.

• Precise NoGo verification for M10x0.5 metric fine threads: Quickly determine if external threads fall outside the 6h tolerance, enabling rapid pass/fail decisions during inspection.
• Rugged hardened steel construction: Built to resist wear and maintain dimensional accuracy through repeated use in demanding environments.
• Easy, intuitive QC checks: Clear, straightforward use helps operators distinguish in-spec from out-of-spec parts with minimal training, reducing inspection time.

This gauge streamlines quality control workflows by delivering consistent, reliable measurements, helping you reduce rework, minimize downtime, and ensure every M10 x 0.5 threaded part conforms to specification across batches and assemblies.
