JBO Thread Plug Gauge is a precision inspection tool engineered for metric fine threads. It’s ideal for engineers, machinists, quality inspectors, and workshop staff who need quick, reliable checks to confirm threaded holes meet exact specifications. Designed for right-hand M2 x 0.2 threads, this Go/No-Go gauge helps ensure parts fit together smoothly and consistently.

With its Go/No-Go design, you can perform fast pass/fail checks in a single step, speeding setup, reducing guesswork, and cutting inspection time in busy production environments. The gauge is built to endure daily use in workshops and labs, delivering steady performance when it’s needed most.

• Two-ended Go/No-Go design for fast pass/fail checks: Quickly verify internal threads in one action, reducing inspection time and rework.
• Hardened steel for durable, long-life use: Built to resist wear and maintain accuracy through thousands of measurements.
• Precise metric fine threading (M2 x 0.2, 5H) for reliable alignment: Specifically matched to right-hand metric fine threads, ensuring consistent results in critical assemblies.

This gauge gives you dependable, repeatable checks that support tighter tolerances, faster workflows, and higher confidence in every threaded connection you inspect.
