The JBO Thread Plug Gauge is a precision tool built for metric fine threads, designed to verify hole threads quickly and reliably. It’s ideal for engineers, machinists, and QC teams who need confidence that components will assemble perfectly when using M36 x 1.5, left-hand threads.

• Go/No-Go design for fast, reliable checks: Quickly determine if a threaded hole meets the required tolerance by confirming what fits (Go) and what shouldn’t (No-Go), reducing inspection time and guesswork.
• Metric fine thread accuracy (M36 x 1.5, 6H, Left Hand): Precisely sized to the exact metric specification, ensuring your holes meet the tight tolerances needed for reliable mating with compatible parts.
• Durable, user-friendly construction: Hardened steel construction delivers long wear life, while the knurled grip provides secure handling and precise alignment during inspections.

With its exact metric sizing and robust build, this gauge supports consistent, repeatable results across production runs. It helps you speed up quality checks, prevent mismatches in assemblies, and maintain tight threading tolerances, so your projects move from inspection to installation with fewer delays and rework.
