The JBO Thread Plug Gauge (NoGo) is a precision inspection tool designed for metric fine threads. It helps manufacturers, technicians, and quality teams quickly verify threaded holes meet exact standards, ensuring reliable assembly and long-lasting performance.

Designed for left-hand metric fine threads and sized M60 x 2 with 6H tolerance, this gauge is built from hardened steel for durability in demanding workshop environments. Precise machining and careful finishing provide consistent, repeatable checks every time.

• Metric Fine NoGo verification: Specifically designed for metric fine threads, this gauge enables quick, pass/fail checks to confirm hole size within tolerance, improving inspection speed and accuracy.
• Hardened steel construction: Durable, wear‑resistant material that maintains tight tolerances through heavy use, reducing replacement needs and downtime.
• Left-hand thread compatibility with clear sizing: Engineered for left-hand metric fine threads (M60 x 2, 6H) with easy-to-read markings and a smooth interface for fast, error‑free setup.

With the JBO Metric Fine NoGo plug gauge, inspectors and machinists gain a reliable tool that streamlines quality checks, minimizes rework, and supports consistent results across batches. Its durable build and precise dimensions help enhance workflow, delivering confidence in threaded-hole inspections in busy production environments.
