The JBO Thread Plug Gauge is a precision inspection tool designed for metric fine threads, including M10 x 0.5 left-hand holes. With its Go/No-Go design, it lets you quickly verify hole accuracy and ensure proper mating with the corresponding component.

This gauge is ideal for machinists, inspectors, and assembly teams who require fast, reliable thread validation.

• Go/No-Go quick verification: The dual-end design lets you rapidly check both the minimum (Go) and maximum (No-Go) limits, speeding up quality checks and helping ensure every part fits as intended.
• Left-hand thread compatibility: Specifically matched to left-handed M10 x 0.5 threads, enabling accurate inspection of those components without guesswork or extra gauges.
• Durable hardened steel construction: Built to withstand regular use in demanding environments, delivering long service life and stable, repeatable measurements over time.

Using the JBO Thread Plug Gauge helps streamline your inspection workflow, reduces rework, and supports consistent thread engagement across parts, contributing to smoother production and reliable assemblies.
