The JBO Thread Plug Gauge (NoGo) - Metric Fine is a precision measuring tool designed to verify internal metric fine threads. With a right-hand orientation for M52 x 1.5 threads and a 6G tolerance, this NoGo plug gauge delivers quick, dependable checks to ensure threaded holes meet exact specifications in demanding environments.

• Metric-fine precision for reliable checks: Specifically calibrated for metric-fine thread sizes (M52 x 1.5) with 6G tolerance, enabling fast go/no-go verification of threaded holes.
• Durable, hardened-steel construction: Built to resist wear and deformation in busy workshops, ensuring long service life and consistent measurements over time.
• NoGo, right-hand orientation for fast tolerance validation: Tailored for right-hand metric threads, helping inspectors quickly identify out-of-tolerance holes and reduce rework.

The JBO Thread Plug Gauge helps streamline quality control and improve throughput. By delivering fast, repeatable Go/NoGo checks for metric fine threads, it reduces inspection time, minimizes rework, and supports reliable assembly across manufacturing, service, and repair environments.
