JBO Thread Ring Gauge (GO) - Metric Fine - Right Hand - 6g - M18 x 1.25

The JBO Thread Ring Gauge (GO) – Metric Fine, Right Hand, 6g, M18 x 1.25 is a precision tool for verifying external thread diameters on fasteners, fittings, and machined parts. Suited for engineers, inspectors, and shop-floor teams, it helps you quickly confirm that a component meets the GO limit for the specified metric fine thread.

Crafted from hardened steel, this ring gauge delivers exceptional wear resistance and long service life in busy workshop environments. Its meticulous machining and intuitive design make it easy to identify properly conforming threads, supporting efficient quality control and precision engineering.

• Durable hardened-steel construction: Built to withstand daily use, resisting wear to provide long-lasting performance in demanding environments.
• Accurate GO verification for metric fine threads (M18 x 1.25, Right Hand): Precisely machined to confirm external thread size against the GO limit, helping you quickly determine if parts fit your standard RH assemblies.
• Easy identification for fast quality checks: Clear geometry and simple handling let inspectors spot conforming vs. non-conforming parts at a glance, reducing inspection time and rework.

Using this gauge streamlines your threaded-assembly checks, speeds up incoming and in-process inspection, and supports consistent, repeatable results across teams. The combination of rugged steel construction and precise metric-fine geometry means you can rely on accurate measurements every shift, improving workflow, reducing downtime, and delivering confidence in every part that leaves the bench.
