The JBO Thread Ring Gauge (NoGo) - Metric Fine - Left Hand - 6g - M22 x 1 is a precision ring gauge designed to verify external threads on metric fine-thread components. Its exact dimensions and robust build provide dependable go/no-go results to confirm threads are within specification.

Designed for professionals across manufacturing, quality control, and maintenance roles, this gauge makes it easy to verify mating threads quickly and confidently, helping you prevent mismatches and rework.

• Go/No-Go accuracy for rapid acceptance checks: Quickly determine whether external M22 x 1 left-hand threads conform to the 6g tolerance by a simple pass/fail check, reducing inspection time and preventing defective parts from advancing.
• Durable hardened steel construction: Built to resist wear and maintain precise tolerances through heavy use in busy workshops, delivering long-lasting performance you can rely on.
• Metric fine, left-hand thread compatibility (6g): Specifically tailored for metric fine threads with left-hand orientation, ensuring accurate verification and consistent results across standard parts.

By using the JBO NoGo gauge, you streamline quality checks, shorten setup times, and increase confidence that every threaded part meets spec. The durable design minimizes wear-related drift and reduces maintenance needs, while the clear go/no-go result supports accurate documentation and traceability in production records. For teams relying on repeatable, precise threading, this gauge helps improve workflow, reduce downtime, and deliver reliable results in every inspection.
