The JBO Thread Ring Gauge (GO) for UNF threads, Right Hand, 2A, 3/8 x 24, is a precision tool designed to verify external thread diameters quickly and reliably. It’s ideal for engineers, machinists, inspectors, and quality teams who need confident pass/fail checks during inspection and assembly.

Crafted from hardened steel for long-lasting performance, this GO gauge delivers consistent, repeatable measurements even in busy shop environments. Its straightforward design makes it easy to identify properly formed threads, supporting standards compliance and precision engineering across manufacturing and maintenance tasks.

• Accurate UNF GO verification: Precisely sized for 3/8 x 24 UNF threads (2A, right-hand) so you can quickly confirm external thread diameters meet the standard with a smooth pass/fail check.
• Hardened steel construction: Built to resist wear and corrosion, delivering durable, long-lasting performance in demanding workshop environments and maintaining calibration over time.
• User-friendly inspection design: Easy to align with the threads and visually confirm conformance, reducing inspection time and improving workflow on QA checks and assembly lines.

Using the JBO GO UNF thread ring gauge helps you streamline quality control, reduce rework, and speed up threaded component inspections. By delivering clear conformance feedback for right-hand UNF threads in the 3/8 x 24 size, it supports dependable assemblies, consistent results, and a smoother manufacturing process across engineering, production, and maintenance tasks.
