The JBO Thread Ring Gauge GO - Metric Fine, Right Hand, 6g, M12 x 1 is a precision tool designed to verify external thread diameters to metric fine standards. It’s ideal for inspectors, machinists, engineers and maintenance teams who need fast, reliable checks to ensure threaded components meet the M12 x 1, right-hand specification.

Crafted from hardened steel, this GO gauge offers durability and wear resistance for daily use in demanding workshops. Its clear go indication makes it simple to identify properly conforming components, supporting quality control and precision engineering across manufacturing, repair, and assembly tasks.

• Fast GO checks for metric fine threads: Quickly confirm that external threads meet the M12 x 1 right-hand standard, enabling fast pass/fail decisions and streamlined inspections.
• Durable hardened steel construction: Resists wear and maintains accurate dimensions even after heavy use, reducing the need for frequent replacement.
• User-friendly grip and engagement: Knurled outer edge and smooth threading engagement make it easy to handle, align, and insert, boosting efficiency in busy environments.

With this gauge in your toolkit, inspections become faster and more consistent, helping you avoid misfits, reduce rework, and shorten production cycles. The rugged build and precise geometry keep calibration stable over time, giving teams confidence that every threaded connection will assemble correctly and perform reliably in the field.
