The JBO Thread Plug Gauge (NoGo) – Metric Fine is a precision tool designed to verify metric fine threaded holes. It’s ideal for engineers, machinists, inspectors, and quality teams who need fast, reliable checks to confirm parts meet exact specifications. Sized for M48 x 1.5 right-hand metric fine threads and built as a NoGo gauge, it helps ensure holes are within tolerance before assembly. Constructed from hardened steel and finished for durability, the gauge resists wear in busy production lines. The knurled body provides a secure grip and precise handling.

• Metric fine precision for NoGo checks: Specifically designed for metric fine threads, this gauge delivers reliable pass/fail verification of internal threads, helping you quickly identify out-of-tolerance holes.
• Hardened steel, long-lasting durability: Built to withstand daily use in demanding environments, offering wear resistance and consistent performance over many inspections.
• Secure grip and quick, repeatable readings: Knurled exterior and precise machining enable confident handling, reducing inspection time and minimizing human error.

Using the JBO Metric Fine NoGo thread plug gauge helps streamline your quality control workflow, ensuring threaded holes meet spec on first pass, cutting downtime, and supporting reliable, repeatable results across production runs.
