The JBO Thread Ring Gauge (GO) in Metric Fine is a precision inspection tool designed to verify external threads on fasteners, fittings, and machined components. Optimized for metric fine threads such as M24 x 1.5 and a right-hand orientation, it provides a clear GO indication to confirm parts meet the required diameter. A knurled outer edge gives you a secure grip for quick, confident use in busy work environments.
Built from hardened steel for durability, this gauge is ready to withstand daily shop wear while maintaining accuracy across many inspections.

• Precise GO verification for M24 x 1.5 metric fine threads: Quickly confirm external thread diameter meets spec with a clear pass/fail indication, helping you avoid misfits and reduce rework.
• Durable hardened steel construction: Engineered to resist wear and maintain accuracy in demanding environments, delivering long service life with minimal maintenance.
• Ergonomic, right-hand use: Knurled grip and balanced design enable secure handling and fast, confident inspections as part of a streamlined workflow.

Using the JBO GO thread ring gauge simplifies your inspection routine by delivering consistent, reliable results for every part. It helps reduce downtime, supports accurate decisions about fit and function, and enhances overall quality control across production and assembly processes.
