The JBO Thread Ring Gauge (GO) - UNF - Right Hand - 2A - No. 5 x 44 is a precision tool designed to verify external UNF threads. Ideal for engineers, inspectors, machinists, and quality teams, it enables fast, reliable checks of the maximum thread size to ensure components meet exact specifications.

Built from hardened steel for lasting durability, this GO gauge stands up to daily use in busy shops, production lines, and QA labs. Its compact ring design and a knurled outer edge provide a secure grip, making insertion, testing, and reading results quick and straightforward.

• Precise GO gauge for UNF Right-Hand 2A: engineered to match No. 5 x 44 thread form, enabling quick, reliable checks of maximum external thread size and ensuring parts meet spec.
• Durable hardened steel construction: resists wear and maintains measurement accuracy in demanding environments, reducing recalibration needs and downtime.
• Ergonomic knurled grip: secure, comfortable handling during setup and measurement, speeding inspections and minimizing handling errors.

This ring gauge supports faster, more consistent quality control by delivering clear pass/fail results for external thread diameters, helping you keep production moving and parts fitting correctly the first time.
