The JBO Thread Ring Gauge (NoGo) is a precision inspection tool designed to verify external metric coarse threads. Specifically configured for Right Hand threads in the M22 x 2.5 size with a 6h tolerance, it helps engineers, machinists, quality teams, and workshop technicians ensure parts meet the exact thread standards required for reliable assembly and performance.

Made from hardened steel for long-lasting durability, this NoGo gauge stands up to daily use in busy shops and production lines while maintaining accurate measurements. It’s user-friendly and delivers quick, decisive checks that clearly indicate non-conforming components, supporting consistent fitment and safer, more predictable results.

• Durable, wear‑resistant construction: Hardened steel design resists wear, maintains accuracy over many inspections, and reduces replacement costs in demanding environments.
• Precise metric coarse NoGo sizing (M22 x 2.5, 6h, Right Hand): Delivers a clear pass/fail check against the maximum permissible diameter, enabling fast, reliable verification of correct thread engagement.
• User-friendly go/no-go inspection: Intuitive checks allow operators to quickly identify out-of-tolerance threads, speeding QC workflows and reducing inspection time.

Using this gauge helps standardize external thread verification, improves inspection throughput, reduces rework and scrap, and provides confidence that metric coarse threaded connections will assemble and function as intended in every batch.
