The JBO Thread Ring Gauge (NoGo) – Metric Coarse, Right Hand, 4h, M22 x 2.5 is a precision inspection tool designed to verify external thread dimensions quickly and reliably. Built for engineers, buyers, tradespeople, and quality-conscious workshop teams, it helps ensure threaded components meet exact standards with simple, confidence-inspiring checks.

Made from hardened steel, this NoGo gauge delivers excellent wear resistance and long-lasting performance in demanding environments. Its metric coarse (M22 x 2.5) size, combined with the 4h tolerance and right-hand thread, provides a clear, repeatable way to confirm correct fitment and detect out-of-spec parts during routine quality control and assembly checks.

• Durable hardened steel construction: Built to withstand daily use in busy workshops, delivering long wear life and consistent results even after frequent handling.
• Precise metric coarse NoGo sizing (M22 x 2.5, 4h, right-hand): Enables fast pass/fail checks to verify external thread dimensions, reducing inspection time and rework.
• User-friendly design with knurled edge for easy handling: Easy alignment and seating during measurement, so you can work quickly with confidence and less fatigue.

Using the JBO Thread Ring Gauge streamlines quality control, improves workflow reliability, and helps ensure that metric coarse threaded connections meet the required standards for optimal fit and performance. It’s a trustworthy tool for precision engineering, manufacturing, and maintenance applications.
