The JBO Thread Ring Gauge (NoGo) is a precision tool designed to verify external metric fine-thread diameters. Specifically configured for right-hand M14 x 1 threads with 4h tolerance, it provides fast, reliable checks to confirm parts meet the required limits.

Ideal for inspectors, machinists, quality-control teams, and maintenance professionals across manufacturing, automotive, and industrial settings. Use it to quickly identify non-conforming threads and ensure compliance with standards.

• Hardened steel construction: Built to withstand daily use, delivering lasting wear resistance and stable, repeatable NoGo checks in demanding environments.
• Precise metric fine thread verification (M14 x 1, right-hand, 4h): Provides clear pass/fail results for external threads, helping you enforce tight tolerances quickly and consistently.
• User-friendly, quick-read design: Easy to handle with intuitive orientation, enabling fast inspections and reducing downtime on busy lines.

By using the JBO Thread Ring Gauge, you streamline your inspection workflow, cut rework, and ensure consistent thread quality across batches. The gauge's durable build, precise metric fine threading check, and straightforward operation translate to fewer rejects, faster approvals, and greater confidence in every component that bears your mark.
