The JBO Ring Gauge NoGo – Metric Fine is a precision external thread gauge built for professionals who inspect threaded components. Designed for right-hand threads and a 6g tolerance class, it provides a reliable means to verify that parts meet the required M108 x 1.5 specification. This gauge is ideal for engineers, inspectors, machinists, and quality teams seeking fast, confident conformance checks.

Constructed from hardened steel for durability, the gauge resists wear in demanding shop environments and maintains accuracy over many uses. The knurled outer edge offers a secure grip for easy handling, while the NoGo designation helps you quickly identify non-conforming threads during routine quality checks.

• Precise NoGo external thread inspection: quickly determine whether threads comply with the NoGo limit, enabling fast pass/fail decisions and reducing inspection time.
• Durable, wear‑resistant hardened steel: built to withstand daily handling and reuse, delivering long service life and consistent performance.
• Metric Fine, right-hand compatibility for M108 x 1.5 (6g): specifically tuned for the M108 x 1.5 right-hand thread, ensuring accurate diameter checks and reliable setup every time.

Incorporating the JBO Ring Gauge NoGo into your QA process helps streamline inspections, minimize rework, and sustain precise, repeatable results across production and assembly workflows. It provides clear, trustworthy measurements you can rely on for compliant, high‑quality threaded components.
