The JBO Thread Ring Gauge (NoGo) is a purpose-built tool for quickly verifying external threads on components with right-hand BSW threading. Sized for a 7/8 in major diameter and 9 threads per inch, it supports precise checks in manufacturing, automotive, and aerospace QA workflows.

Made from hardened steel for durability, this gauge features a dedicated NoGo segment that clearly indicates non-conforming threads, helping you ensure proper fit, reliable performance, and consistent quality across parts.

• NoGo Design for Quick Non-Conforming Thread Detection: The NoGo segment provides an immediate pass/fail indication so inspectors can spot mismatched threads at a glance and halt faulty parts before assembly.
• Hardened Steel Construction for Durability: Built to withstand daily use in busy shops and production lines while preserving measurement accuracy and edge wear resistance.
• Exact 7/8 in x 9 TPI Right-Hand BSW Alignment: Precisely sized for the specified diameter and pitch, ensuring reliable testing against standard right-hand BSW thread profiles.

By integrating this gauge into your inspection routine, you’ll speed up threaded-component checks, reduce downtime, and improve confidence in fitment and performance across critical assemblies. Its robust construction and clear NoGo indication help you maintain consistent results, lower scrap, and support compliant manufacturing processes.
