The JBO Thread Ring Gauge (NoGo) – Metric Fine, Right Hand, 4h, M26 x 0.75 is a precision inspection tool designed to verify external thread diameters on fasteners, fittings, and mechanical components. Built for engineers, quality teams, machine shops, and skilled hobbyists, it provides a clear, repeatable method to confirm whether a part meets the required thread size and tolerance.

Crafted from hardened steel for exceptional durability, this NoGo gauge is designed to withstand daily use in demanding environments while maintaining accurate measurements. Its straightforward design makes it easy to use for quick checks, helping you identify non-conforming components fast and keep production and assembly flowing smoothly.

• NoGo metric fine verification: Delivers decisive pass/fail results for external threads, reducing guesswork and speeding up inspection workflows.
• Hardened steel construction: Built to resist wear and maintain calibration, delivering reliable performance over many uses in busy workshops.
• Right-hand orientation and easy setup: Aligns with standard inspection practices for fast, intuitive use and rapid identification of out-of-tolerance parts.

Using the JBO NoGo Ring Gauge helps you confirm that external threads conform to M26 x 0.75 with the 4h tolerance class, minimizing rework and defects. Its robust construction supports consistent, repeatable measurements across shifts, giving your team the confidence to source, assemble, and certify threaded components with greater efficiency and reliability.
