The JBO Thread Ring Gauge (NoGo) is a precision tool for verifying external metric threads. Specifically configured for right-hand threads with M98 x 1.5 and a fine 6g tolerance, this NoGo gauge helps inspectors quickly determine if a thread is within spec by confirming that the maximum allowable diameter is not exceeded.

Crafted with hardened steel and precisely machined surfaces, the gauge delivers durable, repeatable performance in busy workshops, quality labs, and maintenance environments. Its straightforward design makes it easy to identify non-conforming threads at a glance, supporting efficient quality control and traceability across threaded components.

• Precise M98 x 1.5 NoGo gauge for right-hand threads: Enables rapid pass/fail checks against the specified external thread diameter, reducing inspection time and boosting confidence in tolerances.
• Hardened steel construction for durability: Delivers long service life and wear resistance in demanding environments, ensuring consistent performance over time.
• Fast, user-friendly checks to identify out-of-tolerance threads: Clear, repeatable results that streamline quality checks and minimize rework.

This gauge supports efficient, accurate thread inspection, helping you identify non-conforming components before they enter production lines or assemblies. With its hardened steel build and precise M98 x 1.5 right-hand thread geometry, it delivers dependable results time after time, reducing rework, improving consistency, and strengthening quality control across manufacturing, machining, and maintenance tasks.
