The JBO Thread Ring Gauge (NoGo) is a precision inspection tool for external metric fine threads. Sized M100 x 6 with a 6g tolerance and a right-hand thread, it delivers fast, reliable checks to confirm parts meet specification.

Manufactured from hardened steel, this NoGo ring gauge is built for durability and long service life in busy workshop environments, maintaining dimensional accuracy through repeated use.

• NoGo limit for metric fine threads: Provides quick go/no-go verification of the maximum permissible diameter for M100 x 6, 6g right-hand threads, enabling fast pass/fail decisions and reducing rework.
• Hardened steel construction: Offers exceptional wear resistance and long-term reliability in daily inspection tasks, helping maintain consistent measurements over time.
• Right-hand metric fine sizing (M100 x 6): Specifically tuned to standard metric fine threads, ensuring dependable, repeatable checks for common components and assemblies.

Using the JBO Thread Ring Gauge enhances your inspection workflow by delivering objective, repeatable measurements, reducing downtime from rejects, and supporting consistent quality across production, maintenance, and QA tasks.
