The JBO Thread Ring Gauge (NoGo) – Metric Fine is a precision inspection tool designed to verify external thread diameters on threaded components. It’s an essential instrument for machinists, quality engineers, buyers, and shop-floor technicians who need quick, reliable conformance checks to keep production moving smoothly.

Crafted as a NoGo gauge in metric fine pitch, this tool uses durable construction and precise dimensions to support accurate measurements. Made from hardened steel, it delivers long-lasting performance in demanding environments and makes it easy to identify parts that do not meet the required standards, supporting robust quality control and precision engineering.

• Precise NoGo gauge for metric fine threads: Verifies external thread diameters (e.g., M24 x 1) against the specification, enabling fast pass/fail decisions and consistent part quality.
• Hardened steel construction for durability: Built to resist wear in busy shops, preserving accuracy and extending service life even under tough inspection workloads.
• User-friendly inspection design: Clear, quick identification of non-conforming threads to streamline QA checks and reduce downtime.

By using the JBO Ring Gauge, you gain reliable, repeatable thread checks that improve first-pass quality, shorten inspection cycles, and protect assemblies from mismatched fasteners. The gauge supports standard-compliant manufacturing and precision engineering by catching non-conforming parts early, reducing rework and waste, and helping teams work more efficiently from inspection through final assembly.
