The JBO Thread Ring Gauge (NoGo) is a precision tool designed to verify external threads on metric fine pitch components. Specifically configured for right-hand M23 x 1 threads, this gauge helps machinists, quality inspectors, toolmakers, and serious hobbyists quickly determine if a part’s thread must be rejected or can proceed to the next stage of production.

Crafted for reliability, the gauge uses hardened steel construction to withstand daily use in demanding workshop environments. Its precise dimensions and sturdy build ensure consistent performance, while the NoGo designation makes it easy to spot non-conforming threads at a glance, supporting efficient quality control and accurate engineering.)

• Precise NoGo validation: Quickly flags parts outside tolerance on M23 x 1 right-hand metric fine threads, helping you reject non-conforming components and reduce rework.
• Durable hardened steel construction: Built to endure repeated inspection cycles with excellent wear resistance, delivering long-lasting accuracy in busy shops.
• User-friendly, fast setup: Intuitive orientation and clear sizing enable inspectors to perform checks in seconds, improving workflow and reducing inspection time.

This gauge supports a streamlined inspection process, enabling dependable, repeatable results that improve overall quality and efficiency. By providing clear, reliable feedback on threaded components, it helps you maintain consistent production standards, minimize downtime, and protect your downstream assembly quality.
