The JBO Thread Ring Gauge (NoGo) — Metric Fine, Right Hand, 6g, M140 x 4 — is a precision tool for verifying external thread diameters. It’s ideal for engineers, inspectors, machinists, and quality teams who need quick, reliable checks to confirm threaded parts meet exact standards.

• Precise NoGo verification: Quickly confirms whether the external thread diameter is within the allowed maximum size for metric fine threads, helping you catch out-of-tolerance parts early and keep production moving.
• Durable hardened steel construction: Built to resist wear and maintain accuracy through repeated use, delivering long service life in busy workshops and demanding environments.
• Right Hand, metric fine compatibility: Sized for common M140 x 4 right-hand threads, enabling straightforward, reliable testing that fits into standard quality-control routines.

In practice, the JBO NoGo gauge streamlines your inspection process by delivering clear, repeatable pass/fail results for threaded components. Its rugged build and precise dimensions support consistent quality across batches, reduce downtime, and help ensure assemblies meet spec every time.
