The JBO Thread Ring Gauge (GO) - Metric Fine, Right Hand, 6g, M40 x 2 is a go/no-go tool designed to verify external thread diameters to metric standards. It’s ideal for engineers, machinists, quality inspectors, buyers, tradespeople, and hobbyists who assemble threaded components and need fast, reliable checks.

Built for durability and repeatable accuracy, this gauge features a metric fine GO face that quickly confirms parts meet the M40 x 2 right-hand thread specification. Crafted from hardened steel, it stands up to daily use in busy workshops while maintaining precise measurements and easy identification of conforming components.

• Precise metric fine GO gauge for M40 x 2 threads: Verifies external threads quickly against the GO limit, reducing guesswork and rework.
• Hardened steel construction for durability: Withstands daily shop wear while maintaining accuracy, giving long-lasting performance.
• Right-hand 6g tolerance for reliable readings: Built to standard right-hand thread specs, ensuring consistent, repeatable inspection results.

Using the JBO Thread Ring Gauge streamlines quality control by delivering fast, confident pass/fail checks for external threads. The robust, easy-to-use design helps teams verify component conformity, reduce inspection time, and maintain consistent results across production runs—giving buyers and manufacturers alike greater assurance in every threaded assembly.
