Designed for quality-driven shops, the JBO Thread Ring Gauge (NoGo) – Metric Coarse gives a fast, reliable reference for external thread diameters. Built for Right Hand threads with 4h tolerance and M2.2 x 0.45 pitch, this hardened steel gauge is ready for daily inspection work and helps machinists, inspectors, and assembly teams quickly confirm conformance and identify out-of-spec parts.

• Rapid NoGo conformance checks: Quickly verify that the external thread diameter is within specification, enabling fast pass/fail decisions and minimizing downtime in inspection and assembly workflows.
• Hardened steel construction: Built to withstand demanding shop conditions, resisting wear and maintaining measurement accuracy for long service life.
• Specifically tuned for metric coarse threads (M2.2 x 0.45, Right Hand): Ensures reliable checks on common fasteners and mating parts, reducing setup errors and improving throughput.

With the JBO Thread Ring Gauge (NoGo) – Metric Coarse, your inspection workflow gains a precise, repeatable method to validate thread fitment, cut downtime, and protect assembly quality. The durable construction stands up to everyday use, while the NoGo verification clearly flags non-conforming components and keeps your production on schedule. Whether you are performing incoming, in-process, or final inspections, this gauge provides a trustworthy, straightforward tool to help ensure metric coarse threaded connections meet the required standards for reliable performance and long-lasting connections.
