The JBO Thread Ring Gauge (NoGo) is a precision inspection tool for external threads. This Metric Fine gauge is designed for right-hand threads, sized M28 x 1 with a 6e tolerance, delivering fast, clear go/no-go checks on threaded parts for quick conformance decisions.

Constructed from hardened steel, it withstands daily use in busy workshops and maintains accurate dimensions over time. Its simple, intuitive design makes it easy for any operator to identify non-conforming components and keep production moving.

• Go/No-Go Quick Checks: Instant pass/fail feedback for external threads, speeding inspections and reducing guesswork on tolerances.
• Durable Hardened Steel Body: Built to resist wear in busy workshops, keeping measurements consistent over thousands of cycles.
• Specifically Matched to M28 x 1 Right-Hand Fine Threads: Tailored for your common metric fine-thread applications, ensuring reliable, repeatable results with minimal setup.

Using this NoGo gauge, you can speed up incoming and in-process inspections, reduce rework, and improve overall thread quality across batches. The rugged hardened steel construction and precise internal dimensions ensure repeatable results, while the compact, user-friendly design minimizes operator variance. Invest in a trusted measurement companion that supports consistent, reliable outcomes in demanding environments.
