The JBO Thread Plug Gauge is a precision Go/No-Go tool designed for metric fine threads. Specifically suited for M30 x 0.5 right-hand threads within the 6H tolerance, it lets you quickly validate threaded holes during setup, inspection, and assembly to ensure components fit together as intended.

• Go/No-Go quick verification: Instantly determine whether a threaded hole meets the required metric fine-thread specification, speeding up setup, quality checks, and reducing guesswork.
• Hardened steel construction: Built to withstand daily workshop use, resisting wear and maintaining accuracy for long-lasting, reliable performance.
• Metric fine-thread compatibility (M30 x 0.5, right-hand, 6H): Precisely matched to the target thread type, delivering dependable pass/fail results and reducing rework in precision assemblies.

In practice, this gauge streamlines quality control and assembly workflows by providing clear, immediate results. Its robust build and accurate Go/No-Go evaluation help you avoid mismatches, shorten downtime, and maintain consistent thread engagement across parts, fixtures, and tools.
