The JBO Thread Ring Gauge (NoGo) is a precision inspection tool for external metric threads. It’s specifically designed for metric fine threads, making it ideal for manufacturers, machinists, quality control teams, and service technicians who need fast, reliable checks on M17 x 0.75 threads.

This NoGo gauge features a right-hand orientation and a 6h class, ensuring consistent fit testing against the maximum permitted diameter. Crafted from hardened steel, it resists wear on busy shop floors while maintaining accurate, repeatable results over time.

• NoGo Verification for Metric Fine Threads: Quickly confirms whether external threads exceed the maximum allowed size for M17 x 0.75, enabling fast pass/fail decisions during inspections and QA checks.
• Durable Hardened Steel Construction: Built to withstand daily use in demanding environments, delivering long-lasting accuracy and resistance to wear.
• Right-Hand, 6h Design for Easy, Reliable Use: Ergonomic handling on standard components with consistent alignment, reducing setup time and human error.

Using the JBO NoGo ring gauge streamlines your quality workflow—identifying non-conforming parts quickly, reducing rework, and ensuring consistent thread quality across batches. Its robust construction protects your measurement investment and supports reliable, repeatable results in production and maintenance environments.
