The JBO Thread Ring Gauge (NoGo) – Metric Fine is a precision inspection tool designed to verify external threads on components, specifically for right-hand M9 x 1 threads. It’s built for engineers, machinists, quality teams, and workshop technicians who need quick, reliable checks to confirm parts meet the maximum material condition.

• NoGo verification for external M9 x 1 threads: Quickly confirm that a part’s outer thread does not exceed the maximum limit, helping prevent mismatches and rework.
• Metric Fine, right-hand 6h specification: Specifically tuned for metric fine threads in the right-handed orientation, ensuring reliable, repeatable results across parts that use this standard.
• Hardened steel construction for durability: Built to withstand daily use in demanding environments, resisting wear to maintain calibration and accuracy over time.

With the JBO NoGo ring gauge, inspections become faster and more dependable, reducing guesswork and downtime while improving consistency across batches. Its durable steel construction and precise metric fine specifications help you reliably identify out-of-tolerance parts, supporting tighter quality control and smoother downstream assembly.
