The JBO Thread Plug Gauge is a precision inspection tool designed for metric fine threads. It helps verify internal threads in holes to ensure a proper fit with M24 x 2 fasteners, making it ideal for manufacturing, machining, and assembly environments where thread accuracy matters.

Designed as a Right Hand gauge in 6G tolerance and built from hardened steel, this plug gauge delivers reliable performance in busy workshops and quality-control stations. The Go/No-Go design enables fast, clear pass/fail checks during setup, inspection, or routine maintenance tasks.

• Go/No-Go Design for Quick Hole Checks: Quickly determine whether a threaded hole is within tolerance with a straightforward test, speeding up setup and reducing downtime.
• Metric Fine Thread Compatibility: Precisely checks for M24 x 2 fine thread holes, ensuring correct fit with mating bolts and components.
• Durable Hardened Steel Construction: Built to resist wear and maintain accuracy in daily workshop use, delivering long service life and consistent results.

This gauge helps streamline your threading workflow by providing reliable, repeatable pass/fail results. It minimizes guesswork during assembly, reduces rework, and supports consistent thread quality across parts and batches, giving you confidence in every measurement and every fit.
