The JBO Thread Plug Gauge is a precision Go/No-Go gauge for metric fine threads, calibrated for M29 x 1 right-hand internal threads with 4H tolerance to ensure holes meet exact specs. Built with hardened steel and a knurled grip, it's durable enough for daily shop use and comfortable to handle during quick inspections.

• Go/No-Go Design for Fast, Reliable Checks: Quickly verify whether the threaded hole meets tolerance, delivering clear pass/fail results in seconds and reducing inspection time.
• M29 x 1 Right-Hand Fine Thread Compatibility: Precisely sized for the target metric fine-thread hole, providing accurate go/no-go results for reliable assemblies.
• Hardened Steel Construction for Durability: Built to withstand daily use, resisting wear and maintaining accuracy to extend tool life in busy environments.

Using this gauge, you can speed up quality control, cut down on trial fittings, and improve consistency across parts and production runs. Its robust construction and precise sizing give you confidence that holes will thread smoothly, reducing downtime and rework while improving overall assembly accuracy.
