The JBO Thread Ring Gauge (NoGo) is a precision external thread gauge designed for quick, reliable verification of metric fine threads. Specifically configured for right-hand M76 x 1.5 threads, this 6g gauge helps inspectors and machinists confirm parts meet exact diameters and tolerances.

Crafted from hardened steel and other high‑quality materials, the gauge resists wear in busy workshop environments, delivering long‑lasting accuracy and repeatable results. Its straightforward, user‑friendly design makes it easy to identify when threads are out of tolerance, supporting efficient quality control and precision engineering.

• Exact metric fine thread size (M76 x 1.5) in a Right‑Hand configuration: Provides immediate, accurate verification of external threads, supporting quick pass/fail decisions and compliance with standards.
• NoGo‑style quick assessment for in‑tolerance or out‑of‑tolerance parts: Lets operators identify non‑conforming threads at a glance, reducing guesswork and inspection time.
• Rugged construction for long service life: Built from hardened steel and high‑quality materials to resist wear in busy workshops, delivering consistent readings over time.

By delivering fast, decisive measurements, the JBO NoGo Thread Ring Gauge helps your team maintain tight tolerances, reduce rework, and ensure parts meet exact specifications before they reach downstream processes. It supports streamlined quality control, improves throughput, and provides confidence in reliable, repeatable results across production runs.
