The JBO Thread Ring Gauge (NoGo) - Metric Fine - Right Hand - 6g - M40 x 1 is a precision inspection tool designed to verify external metric fine threads. It’s ideal for engineers, machinists, quality inspectors, and maintenance teams who need fast, reliable checks of threaded components.

With its NoGo design, it helps you verify whether a thread is within tolerance, preventing mismatches before assembly. Built for durability and long life, the gauge supports demanding work environments and repeated use in production or workshop settings.

• Accurate NoGo verification for Metric Fine threads: Quickly confirms if the external thread (M40 x 1, 6g, right-hand) is within tolerance, enabling fast pass/fail decisions and reducing the risk of misfits in assemblies.
• Durable hardened steel construction: Provides excellent wear resistance and a long service life, maintaining measurement accuracy through heavy use in busy workshops.
• User-friendly, right-hand orientation: Clear markings and intuitive handling support rapid inspections and easy identification of non-conforming parts, minimizing downtime and rework.

Incorporating this gauge into your inspection routine delivers faster, more reliable thread checks, streamlined quality control, and consistent results across batches. It supports confidence in your threaded fittings and helps ensure assemblies meet exacting standards without slowing down production.
