JBO Thread Plug Gauge is a precision inspection tool designed for metric fine threads. This Go/No-Go gauge is built for fast, reliable checks of M11 x 0.75 holes, including left-hand configurations, helping engineers, machinists, and QA teams confirm thread fit quickly and with confidence.

• Go/No-Go Quick Verification: Quickly determine whether a threaded hole meets the required tolerance, enabling faster inspections, fewer reworks, and smoother production flow.
• Left-Hand Metric Fine Thread (M11 x 0.75, 6H) Compatibility: Specifically calibrated for left-hand and metric fine threads with 6H tolerance, ensuring accurate readings and preventing misinterpretation during checks.
• Durable Hardened Steel Construction: Built to resist wear from daily use, maintaining accuracy over many cycles and providing long-lasting performance in busy workshop environments.

Designed for reliable, repeatable results, the JBO Thread Plug Gauge helps you verify thread fit with confidence. Its robust construction and targeted design reduce inspection time, support consistent quality across batches, and stand up to the demands of busy manufacturing and assembly settings.
