The JBO Thread Plug Gauge is a precision inspection tool built for metric fine threads. Sized for M24 x 1 with a right-hand 6G fit, it’s ideal for quality checks in manufacturing, machining, and assembly environments where thread accuracy matters. The Go/No-Go design lets you verify internal threads quickly and confidently, so parts fit together as intended.

Manufactured from hardened steel, this gauge delivers durable performance in busy workshops, resisting wear and maintaining accuracy through repeated use. Its robust construction means reliable results you can trust year after year.

• Go/No-Go quick verification: Quickly confirm thread acceptance by testing both the go and no-go limits, reducing inspection time and guesswork during assembly.
• Metric fine-thread compatibility (M24 x 1, 6G, right-hand): Precisely designed for metric fine threads, ensuring accurate hole checks and reliable mating with components that use M24 x 1 threads.
• Durable hardened steel construction: Built to withstand daily use, delivering long-lasting wear resistance and stable measurements even in busy shop environments.

Using this gauge in QC routines minimizes rework, speeds up hole acceptance, and provides clear go/no-go decisions that keep production on track. Its precise, durable design gives you confidence in every inspection and helps you achieve consistent, dependable thread fits across projects.
