The JBO Thread Plug Gauge (GO) – Metric Fine – Right Hand – 6H – M130 x 3 is a precision go gauge designed to quickly verify that threaded holes conform to the M130 x 3 metric fine standard. Ideal for quality control teams, machinists, and engineers, it provides a reliable go/no-go assessment that speeds inspections and helps ensure parts meet specification.

Manufactured from hardened steel for durability in demanding shop environments, this GO gauge resists wear and maintains accuracy through repeated use. Its simple, intuitive design makes it easy to identify whether a hole is properly threaded, supporting consistent QA results across production runs.

• Precise metric fine GO verification: Quickly confirms that a threaded hole accepts the gauge only when within the 6H tolerance and right-hand thread, enabling fast pass/fail decisions and reducing rework.
• Hardened steel construction: Built to endure daily workshop use, resisting wear and corrosion to deliver long tool life and stable, repeatable measurements.
• Ergonomic, user-friendly design: Knurled body and compact profile provide a secure grip and straightforward alignment, even in tight holes or confined workspaces.

Using this gauge helps you improve inspection speed and accuracy, reduce downtime, and ensure consistent thread quality across parts and assemblies. By delivering clear pass/fail results on each hole, it supports tighter process control, fewer rejects, and smoother assembly in manufacturing, automotive, aerospace, and general engineering projects.
