The JBO Thread Ring Gauge (NoGo) is a precision tool used to verify the outer diameter of metric fine threads on fasteners and threaded components. Designed as a NoGo gauge with right-hand orientation, it features an M80 x 2 size and 6g tolerance to ensure accurate conformance checks. Crafted from hardened steel, it offers durability and long-lasting calibration for demanding workshop environments.

• Fast NoGo conformance checks: Quickly determine if a part’s external thread diameter is within the allowed tolerance, helping you reject out-of-spec parts at a glance and reduce rework.
• Hardened steel construction: Built to last in busy workshops, delivering durable accuracy and resisting wear so calibration stays reliable over many cycles.
• Metric fine M80 x 2, right-hand, 6g tolerance: Precisely matched to common external thread sizes, enabling reliable checks across a wide range of parts used in manufacturing, automotive, and aerospace.

The JBO Thread Ring Gauge (NoGo) helps you streamline quality-control workflows by providing a clear, repeatable reference for thread inspection. It reduces inspection time, lowers the risk of misfit components, and supports consistent, standards-compliant results across production runs. With its robust materials and precision construction, you can trust this gauge to perform reliably day after day.
