The JBO Thread Ring Gauge (GO) – Metric Fine is a precision tool designed to verify the outer diameter of metric threads. Built for inspectors, engineers, machinists, and quality teams, it provides a quick, reliable pass/fail check to confirm parts meet the M65 x 2 right-hand thread standard. Designed to the 6e tolerance class for metric fine threads and sized for M65 x 2 right-hand threads, it offers consistent, repeatable results across production runs.

Crafted from hardened steel for durability, this GO gauge resists wear in busy workshops and maintains its accuracy over time. Its simple, intuitive design makes it easy to identify conforming threaded components during incoming inspection, in-process checks, and final QC.

• Immediate Go/Conformance Feedback: Delivers a clear pass/fail indication for external threads in seconds, helping you speed up quality checks and reduce downtime.
• Rugged Hardened Steel Construction: Built to endure daily workshop use, resisting wear and dents that can affect measurements for long-term, reliable performance.
• Metric Fine M65 x 2 Right-Hand Design: Precisely matched to the M65 x 2 right-hand thread form, ensuring accurate verification of components against standard specifications.

Using the JBO GO gauge in your quality workflow helps you quickly verify thread suitability, cut inspection time, and minimize rework. Its durable construction reduces replacement costs and downtime, while the clear go/no-go indication supports consistent results across batches and applications—from manufacturing and assembly to maintenance and repair.
