The JBO Thread Plug Gauge is a precision inspection tool designed specifically for metric fine threads. It’s ideal for applications where exact threading matters and where quick, reliable hole qualification is needed.

With its Go/No-Go design, you can quickly verify that threaded holes meet the specified size, ensuring components fit together without guesswork. Built with hardened steel for long-lasting performance, this gauge stands up to daily shop use.

• Go/No-Go Quick Checks: The Go/No-Go design lets you quickly confirm whether a hole meets its size tolerance, providing a clear pass/fail result to speed up inspection and reduce guesswork.
• Precision for M13 x 0.75 Right-Hand Fine Threads: Specifically sized for metric fine threads (M13 x 0.75, right-hand), ensuring accurate checks and preventing cross-thread errors in mating parts.
• Hardened Steel Durability: Robust steel construction resists wear in busy workshops, delivering long-lasting performance and consistent results over many uses.

This plug gauge helps you streamline quality checks, shorten setup and inspection times, and maintain reliable thread fits across parts. Its durable build and precise Go/No-Go action give you confidence in every measurement, supporting faster, more consistent assemblies and reduced downtime.
