The JBO Thread Ring Gauge (GO) - UNF - Right Hand - 2A - No. 2 x 64 is a precision GO gauge designed to verify external UNF threads. It’s ideal for engineers, machinists, quality inspectors, and maintenance teams who need fast, reliable checks to confirm that a threaded component will properly mate with its counterpart.

Crafted from hardened steel for durability, this gauge resists wear in busy workshops and stands up to repeated inspections. The ring’s smooth entering surface, combined with a robust knurled exterior, provides easy handling and confident use in dusty or gloved-work environments. With its 2A tolerance and right-hand UNF threading, it delivers consistent, repeatable results across demanding applications.

• Accurate UNF GO gauge for 2A right-hand threads: Quickly verify external threads against the Unified National Fine standard, ensuring proper fit and reliable assembly with mating parts.
• Hardened steel construction for long service life: Built to resist wear, maintain dimensional integrity, and withstand heavy use in manufacturing and inspection routines.
• Ergonomic knurled housing for fast, confident checks: Textured grip allows secure handling and swift checks, even with gloves, reducing inspection downtime.

This gauge helps streamline quality control by delivering repeatable go/no-go results you can trust. By confirming thread conformity early in the process, it reduces rework, prevents mismatches, and speeds up assembly. Its rugged construction and precise dimensions support a consistent measurement program across shifts and teams, enhancing overall reliability and workflow efficiency.
