The JBO Thread Plug Gauge (NoGo) in Metric Fine is a precision inspection tool designed to verify internal threads in metric fine sizes. It is specifically calibrated for M60 x 4 right-hand threads with a 6H internal tolerance, helping engineers, machinists, quality inspectors, and hobbyists confirm that threaded holes meet exact limits.

• Accurate NoGo gauge for M60 x 4 metric fine threads: Quickly verify the maximum hole size to prevent oversized threads, speeding up inspections and reducing rework.
• Designed for metric fine, right-hand threads (6H): Ensures compatibility with common fasteners and provides repeatable, reliable measurements across production runs.
• Hardened steel construction with wear-resistant finish: Built to withstand daily use, maintain tight tolerances, and deliver long service life in busy workshops.

This gauge helps streamline quality control, speed up maintenance checks, and improve assembly reliability by delivering clear pass/fail results for critical thread dimensions. With its robust construction and precise sizing, you can trust it to perform consistently, minimize downtime, and support accurate, repeatable results across projects and production lines.
