The JBO Thread Ring Gauge NoGo (Metric Fine, Right Hand, 6g) is a precision tool designed to quickly verify external threads on small components. Ideal for machinists, quality control technicians, toolmakers, and assembly teams, it provides fast, reliable Go/No-Go checks for M3.5 x 0.5 right-hand threads.

Manufactured from hardened steel, this gauge resists wear in busy workshop environments, maintains long-term accuracy, and stands up to repeated use. Its simple, unambiguous design makes it easy to identify non-conforming components during quality control.

• Exact metric fine threads (M3.5 x 0.5): Quickly and reliably verify the outer thread diameter against the M3.5 x 0.5 specification, helping to catch undersized or oversized parts before they proceed to final assembly.
• Hardened steel construction: Built to endure daily shop use, resisting wear and maintaining measurement accuracy over thousands of checks.
• Right-hand 6g NoGo design: Optimized for fast, unambiguous Go/No-Go checks on right-hand threads, enabling confident rejection of non-conforming parts and smoother quality control.

With the JBO Thread Ring Gauge NoGo, you gain a reliable, efficient method to verify thread quality, reduce inspection time, and sustain consistent performance across production workflows. Its robust build and precise sizing support durable, repeatable results, helping you minimize rework and uphold tight threading standards.
