The JBO Thread Ring Gauge (NoGo) is a precision tool for checking external metric threads. This right-hand gauge in M45 x 1 with a 6g tolerance is designed for quick, reliable NoGo checks to verify threads meet the required size. Crafted from hardened steel, it delivers durable, wear-resistant performance for daily inspection work.
Its simple ring design makes it easy to compare against actual threads, helping you spot non-conforming parts fast and keep production moving.

• NoGo verification for fast, reliable checks: Quickly identifies oversized or out-of-tolerance external threads, helping inspectors spot non-conforming parts and keep production moving.
• Durable hardened steel construction: Built to withstand daily use and resist wear, maintaining accuracy over time.
• Metric fine, M45 x 1 with 6g right-hand design: Matches standard metric threads so checks are consistent across components and assemblies.

This gauge enables quick, repeatable verifications of external thread diameters, supporting effective quality control, reducing rework, and ensuring parts fit correctly in assemblies. Use it for incoming inspection, in-process checks, or final QC to help meet standards and keep projects on schedule.
