Description
The JBO Thread Plug Gauge is a dedicated inspection tool for metric coarse threads, specifically M24 x 3. This left-hand, 6G-grade Go/No-Go gauge helps you quickly verify threaded holes and ensure proper fitment in critical assemblies.
- Go/No-Go quick verification: Quickly determine whether a hole falls inside tolerance—no guesswork or disassembly required. This speeds up setup and reduces inspection time on the shop floor.
- Left-hand M24 x 3, 6G compatibility: Specifically designed for left-hand coarse-thread holes in M24 x 3, ensuring accurate checks with the 6G tolerance for reliable fit across components.
- Hardened steel construction: Built to withstand daily use in demanding workshops, resisting wear and maintaining accuracy after repeated insertions and extractions.
With the JBO Thread Plug Gauge, you gain fast, repeatable thread checks that help you avoid misfits, cut downtime, and ensure consistent quality across production runs or field maintenance. The robust build and precise tolerance make it a trustworthy choice for machinists, inspectors, and maintenance professionals who depend on accurate threaded connections.
