The JBO Thread Ring Gauge (NoGo) - Metric Fine - Right Hand - 6g - M38 x 2 is a precision inspection tool designed to verify external thread diameters on fasteners, fittings, and machined components. It’s ideal for engineers, quality teams, workshop technicians, and tradespeople who need reliable Go/NoGo checks during assembly and maintenance. With its NoGo designation, this gauge helps you quickly identify over-sized or out-of-spec threads and support consistent quality control in demanding environments.

Equipped with a hardened steel body and a wear-resistant finish, the gauge delivers durable, long-lasting performance that remains accurate through daily use in busy workshops.

• NoGo quick pass/fail checks: Quickly determine whether a thread exceeds the maximum accepted diameter, enabling fast go/no-go decisions during inspection and reducing rework.
• Hardened steel construction: Durable, wear-resistant ring gauge that withstands daily use in busy shops while maintaining measurement accuracy.
• Metric fine threading for M38 x 2, right-hand: Precisely matched to metric fine threads, ensuring consistent results across components and minimizing measurement variance.

With this gauge, you can inspect threads more quickly, reduce downtime, and maintain consistent quality across batches. The rugged steel build and precise sizing translate into reliable measurements, reducing guesswork and rework while keeping production flowing smoothly.
