The JBO Thread Ring Gauge (NoGo) for Metric Coarse threads is a precision inspection tool used to verify external thread diameters against standard specifications. Specifically configured for right-hand M24 x 3 coarse threads, it’s ideal for quality control labs, machine shops, and assembly lines that require quick, reliable pass/fail checks.

Built from hardened steel for outstanding durability, this ring gauge withstands daily use in demanding environments and resists wear that could compromise accuracy. The NoGo design makes it easy to identify non-conforming parts at a glance, helping reduce rework and ensure reliable fitment across your supply chain.

• NoGo size verification for quick conformity: Enables fast pass/fail decisions by blocking any part that exceeds the maximum NoGo diameter, reducing inspection time and guarding against oversize threads.
• Durable hardened steel construction: Withstands heavy daily use and resists wear, maintaining accurate measurements over time in busy workshops.
• Thread-specific accuracy for M24 x 3 RH coarse, 6e: Calibrated to the metric coarse standard and right-hand orientation to deliver repeatable, dependable checks across compatible components.

Using the JBO NoGo Ring Gauge during routine inspections helps streamline quality control, improve first-pass assembly reliability, and minimize downtime caused by mismatched threads. Its rugged construction and straightforward operation give teams confidence that every threaded connection will meet the required standard, supporting consistent performance in manufacturing, maintenance, and repair workflows.
