The JBO Thread Ring Gauge (NoGo) - Metric Fine - Right Hand - 6h - M1 x 0.2 is a precision inspection tool designed to verify external thread diameters to metric fine specifications. It’s ideal for machinists, quality inspectors, and assembly technicians who need fast, reliable verification of threaded components against exact standards.

Built from hardened steel, this NoGo gauge delivers durable performance in demanding shop environments and maintains dimensional stability through repeated use. With its right-hand threading and tight 6h tolerance for M1 x 0.2, it provides repeatable results that help confirm components meet the precise specifications required for fit and function.

• Metric fine, right‑hand NoGo gauge (M1 x 0.2, 6h): Enables quick pass/fail verification against the exact external thread size and tolerance, reducing inspection time and guesswork.
• Hardened steel construction: Delivers lasting wear resistance and stable measurements in busy workshops, extending tool life and preserving accuracy.
• User-friendly NoGo design for fast conformance checks: Makes it easy to identify non-conforming threads at a glance, supporting efficient quality control and traceability.

By integrating the JBO Thread Ring Gauge into your inspection routine, you gain confidence that each part meets the exact metric fine thread standard before reaching downstream processes. The gauge’s durable construction and clear NoGo criteria minimize rework, shorten inspection times, and help you maintain tight tolerances with predictable, repeatable results.
