The JBO Thread Plug Gauge is a precision Go/No-Go gauge designed for metric fine threaded holes. It’s tailored for left-hand threads like M36 x 2 with 6G internal tolerance, helping you quickly confirm whether a hole accepts the intended component.

With a hardened steel body and carefully finished gauges, it delivers durable, repeatable results for daily use in quality control, manufacturing, or workshop environments.

• Go/No-Go quick verification: Quickly determine accept or reject on threaded holes, saving inspection time and preventing misfits in assemblies.
• Left-hand metric fine thread accommodation (M36 x 2, 6G): Precisely tuned for the specific thread size and orientation, ensuring reliable checks for the intended parts.
• Hardened steel for durable, long-lasting wear: Built to resist wear and maintain accuracy through heavy use in busy shop and QC settings.

Using this gauge streamlines your inspection workflow by providing clear pass/fail signals, reducing setup time, and improving consistency across batches. Its rugged construction supports long-term reliability, so you can rely on accurate thread verification day after day and minimize returns or rework in production.
