The JBO Thread Ring Gauge (GO) is a precision tool designed for fast, reliable inspection of external threads in metric sizes. Specifically configured for metric fine pitches and M42 x 2 threads, this GO gauge helps quality teams verify that components meet exact dimensional standards. Engineered for Right Hand threads and 6g tolerance, it supports consistent go/no-go checks across manufacturing, assembly, and maintenance environments.

Crafted from hardened steel, the gauge resists wear and maintains its dimensions through repeated use, delivering lasting performance in demanding work settings. Its simple, user-friendly design makes it easy to identify conforming parts at a glance, accelerating quality control workflows and reducing ambiguity in inspections.

• Hardened steel construction for lasting accuracy: Built to resist wear and maintain precise dimensions, ensuring reliable checks over many cycles in tough shop environments.
• Metric Fine GO gauge for M42 x 2 threads: Precisely configured to verify external thread diameter and pitch, helping you confirm parts meet strict standards quickly and consistently.
• Easy, grip-friendly design for fast checks: Knurled outer edge and intuitive GO orientation enable confident, one-hand operation and rapid identification of compliant components.

Using the JBO Thread Ring Gauge (GO) streamlines your quality process by delivering clear go/no-go results, reducing rework, and improving traceability in inspections. Its durable construction and precise sizing provide confidence that every threaded part meets your specifications, helping you maintain high-quality assemblies and efficient production workflows.
