The JBO Thread Plug Gauge is a precision inspection tool tailored for metric fine threads. Designed for right-hand M38 x 2 applications with 4H tolerance, it provides fast Go/No-Go checks to verify threaded holes meet exact specs. The dual-ended, knurled body is easy to handle on busy shop floors, helping you verify fits quickly and confidently.

• Go/No-Go quick checks: Quickly determine if a hole meets the exact size and pitch requirements, enabling fast pass/fail decisions and reducing inspection time.
• Hardened steel for durable accuracy: Built to withstand regular use, resist wear, and maintain reliable measurements over many cycles of use.
• Right-hand metric fine thread compatibility (M38 x 2, 4H): Precisely sized for metric fine threads with a known tolerance, ensuring consistent results and dependable performance in critical assemblies.

Using the gauge helps streamline quality control, reduces rework, and supports consistent, repeatable results across threaded components. Its rugged construction and targeted sizing give you the confidence to assemble tight-tolerance parts with confidence, improving workflow efficiency and overall reliability in production and inspection tasks.
