The JBO Thread Ring Gauge (NoGo) - Metric Fine - Right Hand - 6h - M45 x 1 is a precision tool designed to verify external thread diameters against the metric fine standard. It’s ideal for engineers, machinists, quality inspectors, and maintenance staff who need fast, reliable checks to confirm parts meet specified thread dimensions.

Made from hardened steel with a controlled finish for long life, this NoGo ring gauge resists wear in demanding shop environments and maintains accurate measurements after repeated use. The NoGo design lets you quickly identify threaded components that are out of tolerance, helping you prevent misfits from moving into assembly.

• Precise NoGo verification for M45 x 1: Quickly determine whether an external thread is within the specified metric fine tolerance, enabling fast pass/fail decisions during inspection.
• Hardened steel construction for durability: Built to withstand daily use in busy workshops, resisting wear and preserving dimensional integrity over time.
• Right-hand metric fine gauge with 6h tolerance: Delivers consistent, reliable measurements for standard right-hand threads across parts and assemblies.

Together, these features help streamline quality control, reduce inspection time, and ensure reliable fit and performance of threaded components in manufacturing and maintenance workflows.
