JBO Thread Ring Gauge (GO) - Metric Fine - Left Hand - 6g - M23 x 1 is a precision go gauge designed to quickly verify external threads on components with the M23 x 1 metric fine pitch, left-hand thread. Ideal for engineers, machinists, inspectors, and quality teams, it provides fast, reliable go/no-go confirmation to ensure parts meet the required tolerances before assembly or further processing.

• Precise GO Thread Verification: quickly confirm that the external thread diameter and pitch conform to the M23 x 1 metric fine standard, enabling fast pass/fail decisions in busy production lines.
• Hardened Steel Durability: built from hardened steel for exceptional wear resistance, maintaining accuracy through hundreds of inspections in demanding workshop environments.
• Left-Hand, Metric Fine Compatibility: specifically engineered for left-hand M23 x 1 threads, ensuring correct measurement and reducing the risk of using the wrong gauge in mixed-thread assemblies.

With the JBO GO gauge, you gain reliable, repeatable thread checks that streamline quality control, reduce rework, and support consistent threaded assemblies across a range of applications—from mechanical hardware to precision fittings. Its sturdy construction and precise design help your team inspect faster, document results, and maintain accurate standards over time.
