The JBO Thread Ring Gauge (NoGo) is a precision tool designed to verify external metric threads with confidence. It’s a practical choice for engineers, quality inspectors, machinists, and workshop staff who need clear, quick checks to confirm parts meet exact specifications.

Built from hardened steel for superior durability, this gauge resists wear on busy production floors and maintains dimensional integrity over time. A textured knurled edge on the ring provides a secure grip for easy handling, while the metric fine specification (M78 x 1.5, 6g) and left-hand orientation ensure reliable inspection of left-handed threaded components.

• Precise Metric Fine NoGo Gauge (M78 x 1.5, 6g): Delivers reliable pass/fail checks for external threads, enabling quick identification of non-conforming parts and reducing inspection time.
• Hardened Steel Construction: Offers superior wear resistance and long-term dimensional stability, preserving accuracy through repeated use in demanding environments.
• Left-Hand Thread Compatibility: Specifically designed for left-hand threaded components, preventing read errors and improving inspection reliability in specialized applications.

This gauge helps streamline quality control by delivering decisive, easy-to-interpret results, supporting faster setup, reduced rework, and consistent thread accuracy across production runs. With its robust build and precise sizing, you can trust the JBO NoGo gauge to support accurate, repeatable inspections every time.
