The JBO Thread Ring Gauge (NoGo) – Metric Fine, Right Hand, 6h, M2.2 x 0.25 is a precision tool designed to verify external thread diameters quickly and accurately. It’s ideal for engineers, machinists, inspectors, buyers, hobbyists, and workshop teams who need reliable checks to ensure components meet the exact size and fit required by fine-pitch metric threads.

Crafted for durability and long service, this gauge uses hardened steel and a robust finish to resist wear in busy inspection environments. The NoGo design provides a straightforward way to identify non-conforming parts, supporting consistent quality control across production runs.

• Durable hardened steel construction: Resists wear in demanding shop conditions, helping preserve measurement accuracy over countless inspections.
• Precise metric fine sizing (M2.2 x 0.25, 6h): Ground to tight tolerances for reliable external thread diameter checks on small, fine-pitch components.
• Go/No-Go quick-check design for fast non-conformance detection: Enables immediate pass/fail decisions, reducing inspection time and minimizing the risk of assembling out-of-tolerance parts.

Used correctly, the JBO Thread Ring Gauge streamlines quality control, improves workflow, and enhances reliability by delivering quick, repeatable results seed for every batch of threaded components. Its combination of precise dimensions, durable construction, and user-friendly Go/No-Go operation helps teams verify fit and tolerances with confidence, every time.
