The JBO Thread Ring Gauge (NoGo) is a precision tool designed for quick, reliable verification of external metric threads. Ideal for inspectors, machinists, and quality-control professionals, it targets metric fine threads and is specifically tuned for M3 x 0.35 with right-hand orientation and a 6h class reference. This NoGo gauge helps confirm whether a part’s thread diameter meets the required standard, reducing guesswork during inspection and ensuring consistent results on the shop floor.

• NoGo external thread verification for metric fine threads: provides a clear pass/fail check for M3 x 0.35 right-hand threads, speeding inspections and improving part conformity without complicated measurements.
• Hardened steel construction: delivers outstanding wear resistance and long service life in demanding environments, maintaining accuracy over many cycles.
• Right-hand orientation with 6h class alignment: designed to match standard metric fine-thread sets, supporting reliable, repeatable checks that fit into everyday QC routines.

This gauge supports efficient quality control by delivering fast, dependable measurements that help you identify non-conforming parts early, reduce downtime, and maintain consistent performance across production and assembly workflows. Built for durability and ease of use, it enhances precision engineering outcomes without adding complexity to your inspection process.
