The JBO Thread Plug Gauge (GO) is a precision tool designed to quickly verify threaded holes to metric fine specifications. It is ideal for machinists, quality inspectors, and assembly teams who need fast, reliable hole acceptance checks in metalworking, automotive, and manufacturing environments.

Crafted from hardened steel, this GO gauge resists wear in demanding workshops and delivers long-lasting performance. The metric fine thread specification (Right Hand, M112 x 1.5, 6H) ensures compatibility with common holes and threads, and the GO indicator provides a clear pass/fail signal to speed up inspections.

• Hardened steel construction for wear resistance: Built to withstand daily use in busy workshops, delivering consistent measurements over time.
• Metric Fine, right-hand GO gauge (M112 x 1.5, 6H): Precisely matched to your hole size, enabling quick and accurate GO checks during quality control.
• User-friendly GO design for fast, reliable hole checks: Clear identification of acceptable threads helps operators make rapid, confident decisions with minimal rework.

Using this plug gauge in your QC workflow reduces inspection time, lowers the risk of misreads, and supports reliable, repeatable results across batches. It’s a dependable tool that enhances precision engineering, speeds up mounting and assembly, and helps you maintain consistent thread quality from part to part.
