The JBO Thread Ring Gauge (NoGo) is a precision inspection tool designed to verify external UNF threads on fasteners and machined components. This NoGo gauge is sized for Right Hand threads in the No. 2 x 64 range (2A class), making it ideal for manufacturers, inspectors, and shop floor technicians who need quick, reliable pass/fail checks against Unified thread standards.

• UNF Right-Hand NoGo Design: Provides a clear pass/fail indication for external threads, enabling fast, confident identification of non-conforming parts and reducing rework.
• Hardened Steel Construction: Built to withstand daily use in demanding environments, delivering lasting durability and stable, repeatable measurements over time.
• Size-Specific No. 2 x 64, 2A Class: Precisely matched dimensions ensure consistent inspections and easy cross-reference with documentation and standards.

By incorporating the JBO gauge into your inspection routine, you gain faster, more reliable verification of thread diameters, supporting compliance with Unified thread standards and improving overall assembly quality. The robust no-go feature and durable construction help your team achieve consistent results, reduce downtime, and maintain confidence in every threaded connection.
