JBO Thread Plug Gauge is a precision tool designed to verify metric fine threads in holes. Specifically built for the M16 x 0.75 standard, this Right Hand, 6G plug gauge helps machinists, inspectors, and assembly teams confirm threads quickly and accurately.

With a durable hardened steel body and a knurled grip, it stands up to daily workshop use and provides long-lasting wear resistance. The Go/No-Go design lets you determine acceptance at a glance, reducing inspection time and ensuring consistent fits across components.

• Go/No-Go inspection for quick acceptance checks: Quickly determine whether the threaded hole meets the specified limits, reducing guesswork and speeding up quality checks.
• Metric fine-thread compatibility (M16 x 0.75, 6G, Right Hand): Precisely matches standard metric fine-thread holes to deliver repeatable measurements and reliable fits for your assemblies.
• Hardened steel construction with a knurled grip: Built for durability in busy workshops, providing long service life and easy handling even after repeated use.

This gauge helps you streamline setup, improve consistency across parts, and minimize rework. Its robust design and precise Go/No-Go limits give you confidence in every inspection, supporting faster throughput and higher-quality results in your manufacturing or maintenance workflow.
