The JBO Thread Ring Gauge (GO) – Metric Coarse – Right Hand – 6g – M20 x 2.5 is a precision inspection tool used to verify external threads on metric coarse fasteners and components. It’s ideal for engineers, machinists, quality control teams, assembly technicians, and maintenance staff who need fast, reliable go/no-go checks to confirm the M20 x 2.5 standard is met.

Manufactured from hardened steel for lasting durability, this GO ring gauge resists wear in busy workshops and maintains accurate tolerances through repetitive use. Its simple, user-friendly design supports quick checks during production or assembly, helping you reduce delays and avoid mismatched parts.

• Hardened steel construction: Delivers long tool life and wear resistance for repeat use in high-volume environments, helping maintain consistent accuracy over time.
• Precise M20 x 2.5 metric coarse GO measurement: Ensures external threads meet the exact size and pitch, enabling fast, reliable inspections and fewer misreads.
• Right-hand orientation and easy go/no-go checks: Designed for right-hand threads with straightforward pass/fail checks, speeding up quality control and reducing inspection downtime.

Using this gauge in your workflow helps ensure every threaded connection meets industry standards, improves consistency across parts, reduces rework, and supports traceable quality data. It’s a reliable, straightforward tool you can trust for accurate, repeatable inspections.
