The JBO Thread Ring Gauge (GO) for Metric Coarse threads is a precise inspection tool designed for machinists, quality control professionals, engineers, and assembly teams. It provides a quick, reliable way to verify external thread diameters against exact metric coarse specifications, helping ensure parts thread correctly and fit as intended.

• Exact Metric Coarse Thread Compatibility: Quickly confirms M4 x 0.7 external threads meet the intended size and pitch, helping parts assemble smoothly and reducing guesswork in quality checks.
• Hardened Steel Construction for Durability: Built to resist wear from daily use, delivering long-lasting accuracy and consistent performance across many inspections.
• Easy, Reliable GO Gauge Design: Clear go/no-go results streamline inspections, cut downtime, and support repeatable quality across production runs.

Designed to integrate seamlessly into standard inspection routines, this GO ring gauge helps you uphold thread-tolerance standards, speed up workflows, and improve the reliability of threaded connections in critical applications. With its robust construction and precise geometry, you can trust it to deliver consistent results and enhance overall manufacturing quality.
