The JBO Thread Ring Gauge (NoGo) is a compact, precision tool used to verify external thread diameters on small fasteners and precision components. Engineered for metric fine threads, it is ideal for electronics, automotive, machining, and quality-control labs where accurate thread checks prevent misfits and reworks.

With its NoGo design in metric fine, right-hand orientation, and 6e tolerance, this gauge delivers reliable checks that help you confirm parts meet your standards quickly and confidently.

• NoGo limit for quick pass/fail checks: NoGo limit ensures oversized or out-of-tolerance threads are instantly flagged, speeding inspections and reducing rework.
• Durable hardened steel construction: Built to last in busy workshops, resisting wear to keep accuracy after thousands of uses.
• Metric Fine, M3 x 0.35, Right-Hand, 6e tolerance: Precisely matched to small metric threads with standard right-hand orientation, delivering repeatable measurements across parts.

When added to your QC toolkit, this gauge makes thread inspection straightforward and reliable. It helps you quickly confirm fit, reduce scrap, and maintain consistent quality across production runs, even in demanding environments.
