The JBO Thread Ring Gauge (NoGo) is a precision tool designed to verify external thread diameters with confidence. Specifically configured for metric fine threads, it helps inspectors and machinists quickly determine whether parts with M78 x 1 threads meet the required standards. Its right-hand orientation and NoGo style support straightforward pass/fail checks in busy work environments.

Built for longevity, this gauge is crafted from hardened steel to resist wear and maintain accuracy through heavy use. The robust construction stands up to repeated handling, measurement routines, and the rigors of shop floor testing, ensuring dependable performance cycle after cycle.

• Fast NoGo checks for quick quality decisions: Enables immediate identification of non-conforming threads, speeding up inspections and minimizing downtime.
• Rugged hardened steel construction: Delivers durable, long-lasting performance that holds its accuracy even in demanding environments.
• Metric fine-thread specification (M78 x 1, 6g, Right-Hand): Aligns with standard external threads, ensuring reliable, repeatable measurements across parts and suppliers.

Used in quality control, manufacturing, and precision assembly, this gauge helps you streamline workflows, reduce rework, and achieve consistent results. Rely on its precise sizing and durable design to support accurate acceptance testing and dependable part fit in every project.
