The JBO Thread Ring Gauge (NoGo) - Metric Fine - Right Hand - 6g - M31 x 0.75 is a precision inspection tool designed to verify external thread diameters on components, fasteners, and machined parts. It provides a clear, fast way to determine whether a part meets the exact metric fine thread specification, helping quality teams and manufacturers maintain consistent tolerances.

Crafted from hardened steel, this NoGo ring gauge delivers durable, wear‑resistant performance in busy workshop environments. Its right‑hand configuration and the 6g specification ensure reliable measurements for the M31 x 0.75 thread, enabling quick identification of non‑conforming parts and reducing rework.

• NoGo limit for metric fine threads: Quickly confirm non-conforming external threads by testing the diameter against the NoGo limit for M31 x 0.75, enabling fast pass/fail decisions and cleaner QC processes.
• Hardened steel construction: Built to withstand daily use, resist wear, and maintain accuracy across thousands of inspections in workshop settings.
• Right-hand, 6g specification: Specifically matched to common right-hand thread components with a tight 6g tolerance, delivering consistent measurements and dependable results across production runs.

By incorporating this gauge into your QC workflow, you gain a reliable, fast checkpoint for external threads, helping you reduce downtime, cut rework, and improve overall thread fitting accuracy. The durable build and precise NoGo limit provide confidence in supplier quality and finished assemblies, even in high‑volume environments.
