The JBO Thread Ring Gauge (GO) - Metric Coarse, Right Hand, 6h, M33 x 3.5 is a precision inspection tool designed to verify external threads on metric coarse components. It helps machinists, quality inspectors, and engineers quickly determine whether a part’s minimum thread diameter meets the required specification for reliable assembly.

Made from hardened steel for long-lasting durability, this GO gauge stands up to busy workshop use while maintaining accurate measurements. The knurled outer edge provides confident handling and quick orientation, so inspectors can perform repeatable checks with minimal effort.

• Precise GO verification for M33 x 3.5 threads: Confirms the minimum external thread diameter meets spec, enabling fast pass/fail decisions and preventing undersized parts from moving forward.
• Hardened steel construction for durability: Resists wear and maintains accuracy through high-volume use, reducing replacement costs and downtime.
• Right Hand, metric coarse 6h standard: Aligns with common coarse-thread configurations and standard QA workflows, ensuring easy integration and consistent results.

With the JBO Thread Ring Gauge (GO), you streamline quality checks and minimize guesswork. By delivering reliable minimum-diameter verification for M33 x 3.5 metric coarse threads, it helps you speed up mating checks, reduce rework, and maintain consistent performance across production runs.
