The JBO Thread Plug Gauge (NoGo) – Metric Fine is a precision inspection tool designed to verify metric fine threaded holes. Built for right‑hand applications, it conforms to the NoGo limit on M100 x 6 threads with a 6H tolerance, making it ideal for quality checks in machining, manufacturing, and assembly environments.

• Accurate NoGo verification for metric fine threads: Quickly confirm holes do not exceed the NoGo limit, helping to reduce inspection time and rework.
• Rugged hardened steel construction: Delivers long service life and resistance to wear, maintaining accuracy through daily use in demanding shop conditions.
• Right‑hand orientation with M100 x 6, 6H compatibility: Fits standard metric hole threads and delivers consistent, repeatable results across parts and assemblies.

By integrating the JBO Metric Fine NoGo gauge into your inspection routine, you gain a fast, dependable check that helps ensure holes meet the required NoGo limit, minimizes trial fittings, and speeds up setup. The robust hardened steel body stays accurate over time, so you can rely on consistent results across production runs and shifts, improving overall workflow and reducing downtime in demanding environments.
