The JBO Thread Ring Gauge (GO) is a precision tool for verifying external thread diameters on fasteners and threaded components. It helps engineers, machinists, and inspectors confirm that threads meet required standards with speed and consistency. Designed for metric fine threads, including M24 x 1, the GO gauge is built from hardened steel for long-lasting durability in demanding workshops. Its straightforward design makes it easy to identify components that conform to specification, supporting reliable quality control and precise assembly.

• Accurate GO verification for metric fine threads: Quickly determine whether a thread meets the required diameter, reducing guesswork and minimizing rework in production and QA processes.
• Hardened steel, wear-resistant construction: Built to withstand daily use, delivering consistent measurements over time and extending tool life in busy environments.
• User-friendly inspection tool: Clear pass/fail indication and simple handling speed up quality checks and support reliable, repeatable results across teams.

With the GO gauge, inspections become faster and more reliable, helping you maintain tight tolerances and consistent thread quality across all parts. The durable construction reduces downtime and replacement costs, while the intuitive design lowers training time and errors, giving your team confidence in every measurement.
