The JBO Thread Ring Gauge (NoGo) is a precision tool for verifying external thread diameters on metric fine threads. Specifically designed for right-handed M26 x 0.75 threads in the 6g class, this NoGo gauge helps inspectors and machinists confirm conformance quickly and reliably.

Built from hardened steel, it offers durable, wear-resistant performance in demanding workshops and production environments. The NoGo design provides a clear, straightforward indication when a thread is out of tolerance, supporting efficient quality control and precise engineering.

• Accurate NoGo verification for metric fine threads: Quickly determine if external threads meet the 6g/M26 x 0.75 specifications and identify non-conforming parts, reducing inspection time and rework.
• Rugged hardened steel construction: Built to last in busy shop floors, resisting wear and maintaining measurement accuracy through heavy use.
• Specifically matched to Right-Hand M26 x 0.75, 6g class: Designed to integrate with your metric fine-thread parts, delivering consistent, reliable measurements every time.

With the JBO NoGo Gauge, you gain a straightforward, repeatable check you can rely on across batches—from development to production. Its rugged construction and clear non-conformance indication help reduce scrap, speed inspections, and ensure threaded components consistently meet your specifications.
