The JBO Thread Plug Gauge is a precision inspection tool designed for metric coarse threads. Specifically suited for ensuring holes accept M10 x 1.5 fasteners, this go/no-go gauge helps engineers, machinists, and quality teams quickly confirm correct thread readiness without guesswork.

Built to endure the rigor of daily workshop use, this gauge is crafted from hardened steel for long-lasting performance and stable measurements in busy production environments.

• Go/No-Go verification for fast, reliable checks: Quickly determine if a threaded hole meets the exact size requirement, reducing inspection time and minimizing rework by clearly signaling pass or fail on each measurement.
• Durable hardened steel construction: Designed for repeated use, wear resistance, and stable accuracy even after heavy handling, drops, or tool changes.
• Metric coarse thread focus (M10 x 1.5): Precisely calibrated for standard metric coarse threads, ensuring correct hole size and dependable fit for common fasteners in machining, assembly, and maintenance tasks.

Using the JBO Thread Plug Gauge integrates smoothly into quality controls and assembly workflows. It helps speed up inspections, improves consistency across parts, and gives you confidence that threaded connections will thread in smoothly and perform as intended.
