Designed for metric coarse threads, the JBO Thread Plug Gauge lets technicians quickly verify hole readiness. It features a right-hand M6 x 1 configuration with a 4H tolerance to support consistent, repeatable checks in quality-control workflows.

• Go/No-Go inspection design: Enables fast pass/fail checks for metric coarse-thread holes, helping you confirm acceptance or identify needed rework in seconds.
• Hardened steel construction: Built to withstand daily use in busy shops, delivering long-lasting accuracy and durable performance under repeated insertions and extractions.
• M6 x 1 coarse-thread with 4H tolerance: Aligns with standard metric holes, ensuring consistent size checks and reliable fitment across parts and assemblies.

Using this gauge in your inspection routine speeds hole checks, reduces rework, and helps ensure every M6 x 1 threaded hole meets standard size and fit requirements, improving overall workflow and part compatibility.
