The JBO Thread Plug Gauge – Metric Fine Go/No-Go is a precision inspection tool designed for metric fine threads (M10 x 0.5). It’s ideal for machine shops, manufacturing lines, and quality control teams who need quick, reliable verification that threaded holes will accept the right mating components. With its Go/No-Go design, you can confirm fit and function at a glance, helping you keep assemblies moving smoothly.

• Go/No-Go ends for fast checks: Instantly determine pass/fail conditions on the thread hole, reducing inspection time and preventing misfits in downstream assembly.
• Hardened steel body with knurled grip: Built to endure daily use in demanding environments while maintaining accuracy and providing a secure, non-slip grip during checks.
• Right-hand M10 x 0.5, 4H tolerance: Aligns with standard components and mating threads, delivering consistent, reliable readings across production runs.

Using this gauge streamlines quality checks, shortens setup times, and enhances confidence in threaded connections. Its durable construction and clear Go/No-Go indications help reduce rework and downtime, supporting precise, repeatable results from start to finish.
