The JBO Thread Plug Gauge is a precision go/no-go tool designed for metric coarse threads. This Left Hand (LH) version targets M2.2 x 0.45 threads with a 6H tolerance, enabling fast, reliable checks of threaded holes during setup, assembly, and quality control.

Crafted from hardened steel for long wear life, it features a knurled grip for secure handling and a dual-ended design that lets you inspect threads from different angles without swapping tools.

• Go/No-Go design for quick, reliable checks: Quickly determine if the hole’s thread fits within the 6H tolerance, reducing inspection time and rejecting parts that don’t meet spec.
• Left Hand variant for LH metric coarse threads: Specifically configured to match left-hand M2.2 x 0.45 threads, ensuring accurate measurements and reliable pass/fail results.
• Hardened steel construction with a secure grip: Built to withstand rigorous use in busy shops, delivering durable, repeatable readings over many cycles.

This gauge helps streamline quality workflows by delivering consistent, confident readings that minimize rework and speed up assembly, so you can maintain tight thread tolerances across production runs.
