The JBO Thread Plug Gauge (NoGo) – Metric Fine is a precision measuring tool designed for metric fine threads. This NoGo gauge is tailored for left-hand threaded holes and sized for M72 x 1.5 with a 6H tolerance, making it a reliable choice for inspecting threaded holes across manufacturing, machining, and quality-control environments.

• Metric Fine threading design: Specifically engineered for metric fine threads, enabling precise inspection of M72 x 1.5 holes and ensuring measurements align with fine-thread standards.
• Left-Hand thread compatibility: Built to verify left-hand threaded holes without cross-contamination from right-hand gauges, delivering accurate NoGo checks for specialized assemblies.
• Hardened steel construction: Crafted from durable hardened steel for excellent wear resistance, maintaining long-lasting accuracy in demanding work settings.

This gauge helps you quickly confirm that internal threads meet the required standards, reducing rework and inspection time. With robust construction and precise dimensions, it supports consistent quality across batches and reliable performance in everyday use on the shop floor or in the quality lab.
