The JBO Thread Ring Gauge (GO) for Metric Coarse is a precision go gauge designed to verify external threads quickly and confidently. Sized for M30 x 3.5 with right-hand threads and 6e tolerance, it helps inspectors, engineers, and shop personnel ensure parts meet exact metric coarse thread specifications across manufacturing, quality control, and service environments.

Made from hardened steel, this gauge delivers exceptional durability and wear resistance for daily use in busy benches and production lines. Its straightforward, easy-to-use design supports fast, repeatable inspections, helping teams confirm proper fitment and function of metric coarse threaded connections in line with industry standards.

• Precise Go Verification for M30 x 3.5 (Right-Hand, 6e): Enables reliable go/no-go checks that quickly confirm parts meet exact thread specifications, reducing rework and downtime.
• Hardened Steel Construction: Delivers long-lasting durability and wear resistance, maintaining accuracy through heavy use and daily QC routines.
• User-Friendly, Consistent Inspections: Designed for easy alignment with threads and clear reads, supporting repeatable results across lots and batches.

With the JBO GO Ring Gauge, you can accelerate quality checks, ensure consistent thread fitment, and maintain high standards across production runs. The rugged construction and precise dimensions provide confidence in every measurement, helping you deliver reliable assemblies and reduce costly deviations.
