The JBO Thread Plug Gauge (NoGo) provides a straightforward way to verify metric fine left-hand threads during quality checks. Designed for M62 x 1.5 threads in the 6H tolerance class, it helps confirm that threaded holes meet required specifications without passing parts that fall outside acceptable limits.

• Accurate Limit Checking: The NoGo design quickly identifies threads that exceed the upper size limit, helping maintain consistent quality across production batches.
• Long-Lasting Accuracy: Constructed from hardened steel, the gauge resists wear so it continues to deliver reliable results even after frequent use in busy workshops.
• Secure Handling: The knurled grip offers a firm hold during insertion and removal, reducing the chance of slippage and supporting steady, repeatable measurements.

By catching out-of-spec threads early, this gauge helps reduce scrap, avoid assembly issues, and keep inspection routines efficient for both high-volume manufacturing and smaller precision jobs.
