The JBO Ring Gauge (GO) - Metric Fine - Right Hand - 4h - M12 x 1.25 is a precision tool designed for fast, accurate verification of external thread diameters. It’s ideal for engineers, quality inspectors, machine shops, and maintenance teams who need reliable conformance checks for metric fine threads.

Crafted for durability and long life, this GO gauge uses hardened steel to resist wear in busy workshop environments. Its precise geometry supports consistent measurements, helping you quickly confirm that threaded components meet the M12 x 1.25 standard and pass your quality-control criteria.

• Precise GO verification for metric fine threads: Enables quick, reliable checks of external thread diameters to ensure parts conform to the M12 x 1.25 specification and pass standard inspection criteria.
• Hardened steel construction: Delivers exceptional wear resistance and long-lasting performance in demanding environments, reducing replacement costs and downtime.
• User-friendly conformance checks: Plainly indicates whether a threaded component is within tolerance, speeding up inspections and minimizing confusion during QC processes.

Incorporating this ring gauge into your workflow helps streamline quality control, cut inspection time, and deliver consistent threading results across production runs. Trustworthy construction and precise design provide confidence from first part to last, making every measurement a reliable step in your precision engineering process.
