The JBO Thread Ring Gauge (NoGo) is a precision external-thread inspection tool for metric fine threads, sized for M125 x 4 with a right-hand thread in the 6g class. Crafted from hardened steel, it delivers durable, repeatable NoGo checks for accurate verification of thread diameters. The knurled outer edge provides a secure grip, and the gauge’s clear orientation helps inspectors quickly identify non-conforming threads in busy production environments.

• NoGo sizing for quick pass/fail decisions: This gauge lets you identify threads that exceed the maximum size at a glance, speeding up inspections and reducing rework.
• Durable hardened steel construction: Built to withstand daily use in demanding environments, it resists wear and maintains accuracy over time.
• Metric Fine compatibility — M125 x 4, right-hand: Specifically designed for common metric fine threads, ensuring reliable, repeatable checks with the correct threading orientation.

In daily QA and assembly workflows, this NoGo ring gauge helps you confirm thread compatibility quickly and confidently, reducing guesswork and ensuring parts meet spec before they move to the next step. Its robust materials and precise finish deliver consistent measurements, lower downtime, and repeatable results you and your team can trust.
