The JBO Thread Plug Gauge is a precision tool designed for metric fine threads, enabling quick Go/No-Go verification of threaded holes. It's ideal for engineering shops, maintenance teams, and DIY projects that require reliable, on-the-spot thread checks.

Built for durability, the gauge uses hardened steel to withstand daily use and resist wear, delivering long-lasting accuracy. Its right-hand orientation and 4H tolerance align with the M12 x 1.5 thread standard, ensuring consistent results across common metric hardware.

• Go/No-Go accuracy for metric fine threads: Quickly verify hole size and thread fit with a clear pass/fail result, speeding inspections and reducing guesswork.
• Durable hardened steel construction: Designed for repeated use in busy workshops, providing lasting performance and stable measurements over time.
• Right-Hand orientation with M12 x 1.5, 4H specification: Ensures compatibility with standard metric holes and threads, promoting reliable assembly and fewer mismatches.

With the JBO Thread Plug Gauge, you’ll streamline your threading checks, cut down downtime, and improve overall quality of threaded assemblies. The combination of Go/No-Go clarity and durable construction helps you trust every measurement and keep production moving smoothly.
