The JBO Thread Plug Gauge is a precision Go/No-Go tool designed for metric fine thread inspection. Specifically built for right-hand M9 x 0.75 threads, it helps machinists, inspectors, and assembly teams confirm hole accuracy quickly and with confidence. With its 6H tolerance, you can trust consistent results across parts and batches.

Crafted from hardened steel, this gauge resists wear in demanding workshop environments, delivering long service life and reliable performance even in high-volume production.

• Go/No-Go design for fast, reliable checks: Quickly verify whether a threaded hole meets spec by testing go (inserts) and no-go (does not insert) limits, reducing inspection time and rework.
• Metric fine thread compatibility: M9 x 0.75, right-hand: Precisely sized gauging for common metric fine-thread holes; ensures mating parts fit smoothly and consistently across parts.
• Hardened steel construction for durability: Built to withstand daily use, resist wear, and maintain accuracy over many measurements.

This plug gauge supports streamlined quality control by delivering quick, repeatable checks that help you ensure correct thread engagement, reduce downtime, and improve overall assembly reliability. Its robust construction and precise Go/No-Go limits give teams the confidence to pass parts on first inspection.
