The JBO Thread Ring Gauge (NoGo) – Metric Fine, Right Hand, 6g, M6 x 0.75 is a precision external-thread gauge designed to quickly verify the diameter of M6 x 0.75 fasteners and threaded components. Ideal for quality-control labs, machine shops, and maintenance teams, it helps inspectors confirm parts meet exact size requirements for reliable mating and performance.

Manufactured from hardened steel for exceptional durability, this NoGo gauge resists wear in busy production environments. Its simple, intuitive design makes it easy to identify non-conforming parts at a glance, supporting efficient checks and consistent results across your workflow.

• Go/No-Go quick checks: Quickly determine whether an external M6 x 0.75 thread is within specification, speeding inspections and reducing bottlenecks.
• Hardened steel construction: Built to withstand daily use, delivering long service life with reliable wear resistance.
• Right-Hand metric fine precision (6g): Specifically matched for right-hand metric fine threads, providing repeatable, consistent checks and confidence in part quality.

By delivering fast, accurate size checks, the JBO Ring Gauge minimizes guesswork and rework, improves testing throughput, and helps ensure fasteners and threaded components perform as designed in assemblies. Its robust construction and clear, direct readings support steady quality control, smoother workflows, and greater confidence when sourcing or approving parts for production.
