The JBO Thread Ring Gauge (NoGo) is a precision inspection tool designed to verify external threads on components with metric fine pitch. Specifically configured for M80 x 1 right-hand threads, it helps engineers, machinists, and quality-control teams quickly confirm that parts meet exact size and thread standards.

Crafted from hardened steel, this ring gauge delivers durable, long-lasting performance in busy workshop environments. Its NoGo designation makes it easy to identify non-conforming threaded components, supporting efficient quality control and consistent, reliable results.

• Fast Go/No-Go verification: Quickly confirm external threads are within tolerance, accelerating inspections and reducing rework.
• Durable hardened steel construction: Built for daily use and wear resistance, maintaining accuracy across many cycles in demanding environments.
• Easy identification of non-conforming threads: The NoGo design helps inspectors spot out-of-spec parts at a glance, boosting confidence and speeding workflows.

Using the JBO Thread Ring Gauge helps streamline your quality-control process: it provides quick, reliable pass/fail decisions, minimizes interruptions from misfits, and protects downstream assembly quality. The rugged construction ensures this gauge stays accurate longer, delivering consistent results across multiple jobs and operators.
