The JBO Thread Ring Gauge (GO) - Metric Fine - Right Hand - 6g - M135 x 2 is a precision GO gauge designed to verify external thread diameters to metric fine standards. It’s an essential tool for engineers, machinists, quality inspectors, and workshop technicians who need quick, reliable acceptance checks to ensure threaded components meet exact specifications.

Crafted from hardened steel with a durable finish, this ring gauge stands up to daily use in busy shops and production environments. Its straightforward design makes it easy to use and read, helping you identify properly conforming threads during routine inspections and quality-control cycles.

• Durable hardened-steel construction: Built to resist wear and maintain accurate measurements over many cycles, reducing the need for frequent recalibration and extending the gauge’s service life.
• Metric fine, right-hand specification (M135 x 2, 6g): Precisely matched to metric fine thread forms and right-hand threads, ensuring consistent, reliable checks across compatible components.
• Go (GO) gauge for fast, clear acceptance: Enables quick pass/fail decisions on threaded parts, speeding inspections and minimizing rework with decisive results.

Using this Go thread ring gauge helps streamline your QC workflow, improves measurement consistency, and supports dependable assemblies across your operations. Its robust build and precise tolerances give you confidence in every check, from routine production to critical quality-control applications.
