The JBO Thread Ring Gauge (NoGo) - Metric Fine - Right Hand - 6g - M135 x 4 is a precision inspection tool designed to verify external thread diameters quickly and reliably. Ideal for inspectors, machinists, quality teams, and maintenance professionals, it helps ensure threaded components meet exact standards across manufacturing and repair environments.

• Durable hardened-steel construction: Built from hardened steel to resist wear, maintain dimensional accuracy, and withstand daily use in busy workshops.
• Precise Metric Fine, right-hand threading: Specifically sized for M135 x 4 with a 6g tolerance and right-handed orientation, delivering consistent measurements across parts and compatibility with standard fasteners.
• NoGo-style quick conformance checks: The NoGo design provides a clear pass/fail indication for out-of-spec threads, speeding up QA checks and reducing guesswork on the shop floor.

Together, these features empower you to validate threads with confidence, streamline your inspection routine, and minimize rework. The gauge’s robust build and precise sizing help you sustain accuracy through high-volume production, supplier audits, and complex assemblies, improving overall workflow, consistency, and product quality.
