The JBO Thread Ring Gauge (GO) - UNS - Right Hand - 2A - 1 3/8 x 8 is a precision GO gauge designed to measure external thread diameters and verify compliance with required standards. Crafted from hardened steel for lasting durability, it is built for engineers, inspectors, machinists, and quality teams who need fast, reliable checks to confirm threaded components meet exact specifications.

• Accurate external thread verification: Quickly determine whether a thread diameter conforms to the 1 3/8 x 8 GO standard, enabling fast pass/fail decisions during inspection and reducing rework.
• Durable hardened steel construction: Crafted from high-quality hardened steel to resist wear in demanding shop environments, delivering long service life and consistent performance over time.
• User-friendly inspection design: Clear geometry and intuitive handling help operators identify conforming parts quickly, streamlining quality control and minimizing inspection time.

This gauge supports efficient quality control workflows by providing reliable, repeatable measurements for threaded components. Its rugged construction and precise dimensions help you maintain consistent results in production and inspection environments, giving you confidence to move from inspection to assembly with less rework and greater throughput.
