JBO Thread Ring Gauge (GO) - Metric Fine is a precision tool for checking external threads. Built for right-hand, metric-fine threads such as M28 x 0.75, it speeds up inspection by quickly confirming whether a component’s threads conform to the target size.

• Precise GO-side verification: Delivers accurate measurement of external threads, enabling fast pass/fail decisions during inspections and helping parts meet required standards.
• Durable hardened steel construction: Withstands daily shop wear and resist scuffing, delivering reliable performance and long service life in demanding environments.
• Designed for M28 x 0.75 right-hand, metric-fine threads: Precisely sized to match your target thread, ensuring quick, reliable conformity checks on standard components.

With this gauge, quality teams shorten inspection times, reduce rework, and maintain tighter tolerances across production runs. Its rugged build and precise geometry support consistent results, providing confidence in every threaded assembly you produce.
