The JBO Thread Plug Gauge (NoGo) - Metric Fine, Right Hand, 6H, M42 x 1 is a precision inspection tool designed to verify metric fine threaded holes. It’s built for engineers, machinists, quality control teams, and workshop professionals who need reliable upper-limit checks to ensure threaded holes will accept the correct fasteners and components.

Crafted from hardened steel with a knurled, easy-to-grip surface, this NoGo gauge stands up to daily use in demanding environments. The Metric Fine 6H specification (M42 x 1) ensures precise, repeatable measurements across production runs, helping you maintain tight tolerances without guesswork.

Metric Fine 6H thread precision: Specifically designed for M42 x 1 metric fine threads, enabling quick, reliable Go/NoGo checks to verify hole size and tolerance.
NoGo quick tolerance verification: Helps identify out-of-tolerance holes fast; if the NoGo gauge threads in, the hole is not within spec, saving inspection time and reducing rework.
Durable hardened steel with secure grip: Built to resist wear and corrosion in busy workshops; knurled surface provides secure handling for repeatable measurements over time.

The JBO Metric Fine NoGo Thread Plug Gauge supports consistent, confident inspections, helping you speed up QA checks, reduce scrap, and ensure threaded holes meet your specifications every time.
