The JBO Thread Ring Gauge (NoGo) – Metric Fine is a precision tool designed to verify external thread diameters quickly and reliably. Made for professionals across manufacturing, quality control, engineering, and workshop environments, it helps confirm that M68 x 2 threads meet the required size and tolerance. The NoGo designation means it’s used to identify non-conforming parts so you can act fast.

Crafted from hardened steel and finished for wear resistance, this gauge is built to last in demanding settings. Its right-hand, metric fine specification supports common industrial thread sizes, delivering consistent checks over many cycles and reducing rework on the line.

• Fast NoGo verification: Quickly identifies non-conforming external threads, speeding up inspections and reducing scrap.
• Durable hardened steel construction: Built to resist wear and maintain accuracy in busy shop environments, ensuring long service life.
• Metric Fine compatibility (M68 x 2, right-hand): Designed to match standard metric fine threads, providing reliable, repeatable checks with easy handling on the shop floor.

This gauge helps streamline your workflow by delivering quick, repeatable checks that lower downtime and returns. Whether you’re setting up a production line, performing incoming inspection, or verifying repairs, the JBO NoGo ring gauge gives you confidence that every threaded component meets your specifications. Its robust materials and precise design translate to fewer rework cycles, consistent results, and a safer, more efficient manufacturing process.
