The JBO Thread Ring Gauge (GO) – Metric Coarse, Right Hand, 6g, M9 x 1.25 is a precision inspection tool designed to verify external threads on metric coarse fasteners. It helps machine shops, contract manufacturers, and quality control teams quickly determine if parts will thread properly and assemble without interference. This Go gauge is ideal for ensuring components meet tight M9 x 1.25 specifications and align with standard industry tolerances.

Made from hardened steel for exceptional durability, this Go gauge resists wear in busy workshops and maintains accurate measurements through repeated use. Its compact, purpose-built design makes it a reliable addition to any QC kit, enabling consistent inspections in high-volume environments and helping you uphold industry standards with every check.

• Precise Go/No-Go verification for metric coarse threads: Quickly confirm external thread fit on M9 x 1.25 components, reducing guesswork and rework while speeding up quality checks.
• Durable hardened steel construction: Built to withstand daily use in demanding environments, maintaining accuracy and extending tool life across many inspections.
• Right-hand, metric coarse compatibility (M9 x 1.25, 6g): Specifically designed for common metric coarse threads and right-hand applications, delivering consistent measurements across parts and production runs.

With the JBO Thread Ring Gauge, your team gains faster, more reliable thread inspections that translate to fewer fit issues and less downtime. The Go gauge provides clear pass/fail results, supports standardized QC workflows, and helps you uphold tight tolerances across production—whether you’re building precision assemblies, maintaining equipment, or vetting new components.
