The JBO Thread Ring Gauge (NoGo) - Metric Coarse - Right Hand - 6g - M2 x 0.4 is a precision tool designed to verify the external thread diameter of metric coarse threads. It is ideal for engineers, machinists, quality control professionals, and assembly teams who need fast, reliable confirmation that a threaded part meets the designated NoGo limit.

Made from hardened steel for durable, long-lasting performance, this NoGo ring gauge provides clear pass/fail feedback that makes it easy to identify non-conforming threaded components without guesswork. Its simple, purpose-built design supports quick inspections in busy workshops and QA stations.

• Precise NoGo verification for metric coarse threads: Quickly confirm the external diameter against the NoGo limit for M2 x 0.4 right-hand threads, helping you reject undersized or oversized parts at a glance.
• Durable hardened steel construction: Built to endure daily workshop use, maintaining accuracy and resisting wear to extend the life of the gauge.
• Fast, user-friendly inspection: Clear, simple pass/fail assessment that reduces inspection time and minimizes downtime in quality control or assembly workflows.

In practical terms, the gauge speeds up inspection routines, reduces downtime, and improves the reliability of threaded assemblies. With robust construction and precise NoGo verification, you can trust that M2 x 0.4 metric coarse threads will fit and function as intended, helping your team achieve consistent quality and smoother production flows.
