The JBO Thread Ring Gauge (NoGo) - Metric Fine is a precision inspection tool designed to verify external metric threads with repeatable accuracy. It’s ideal for engineers, machinists, quality inspectors, and workshop teams who need fast, reliable checks of thread diameters to ensure parts meet specification.

Crafted from hardened steel, this NoGo gauge offers lasting durability in demanding production environments. Its right-hand orientation and metric fine sizing (M2 x 2, 6h) align with standard inspection workflows, enabling quick, confident pass/fail decisions during routine quality checks.

• Hardened steel construction for long service life: Built to resist wear and retain dimensional accuracy even after frequent use in busy workshops.
• Metric Fine NoGo gauge for quick pass/fail checks: Precisely sized for M2 x 2 threads with 6h tolerance, providing fast, reliable confirmation of conformance for external threads.
• Right-hand orientation for streamlined inspection: Designed to match common right-hand thread components and inspection processes, helping you complete checks faster with less setup.

This gauge helps you tighten quality control across incoming parts, in-process assemblies, and final products. By delivering consistent results and a clear non-conformance signal, it reduces rework, speeds up QA cycles, and supports reliable, repeatable manufacturing outcomes.
