The JBO Thread Ring Gauge (NoGo) — Metric Coarse, Right Hand, 6g, M4 x 0.7 — is a precision inspection tool designed to streamline external thread inspections. Ideal for quality control teams, machine shops, and field technicians, it helps verify that your fasteners and threaded components meet exact thread diameter limits before assembly.

Made from durable materials like hardened steel, this NoGo ring gauge is built to endure demanding work environments and resist wear over time. It provides quick, reliable identification of non-conforming parts, supporting repeatable measurements and helping keep production moving with fewer rechecks.

• NoGo verification for metric coarse threads: Efficiently checks external thread diameters against the NoGo limit, helping you quickly identify parts that do not meet the M4 x 0.7 coarse thread standard and prevent incorrect assemblies.
• Durable hardened steel construction: Built to endure daily use in demanding environments, offering excellent wear resistance and long service life.
• Right-hand configuration for standard applications: Specifically suited for common right-hand metric coarse threads, ensuring consistent and reliable measurements across projects.

By integrating this gauge into your inspection routine, you can speed up quality checks, reduce rework due to thread tolerance issues, and ensure consistent fit and function for metric coarse threaded connections. Its robust build and clear NoGo detection support quality control, precision engineering, and manufacturing environments, delivering reliable performance day after day.
