The JBO Thread Ring Gauge (NoGo) – Metric Fine, Right Hand, 6e, M55 x 1 is a precision inspection tool used to verify the external thread diameter of components with metric fine threads. It serves professionals across manufacturing, machining, quality control, and maintenance who need fast, reliable go/no-go checks on threaded parts.

Manufactured from hardened steel for durability, this gauge resists wear in busy shop environments and maintains accurate dimensions over time. Its right-hand orientation and clear construction make it easy to identify non-conforming parts, helping you enforce dimensional standards quickly and confidently.

• Exact NoGo verification for M55 x 1, 6e metric fine threads: Quickly confirm that the external thread diameter falls within the NoGo limit, speeding up quality checks and reducing the risk of passing out-of-spec parts.
• Hardened steel construction for long life: Built to withstand daily use in busy shops, resisting wear and maintaining measurement accuracy over many cycles.
• Right-hand orientation and ergonomic design: Easy to handle and align on threaded parts, speeding up setup and reducing operator fatigue during inspections.

By using this gauge, your inspection process becomes faster and more reliable. Expect shorter test times, fewer rework cycles, and better consistency in thread quality across production runs. The durable hardened steel construction ensures the gauge maintains its accuracy after repeated use, giving you confidence in every measurement and every batch.
