The JBO Thread Ring Gauge (GO) - UNS - Right Hand - 2A - 2 x 12 is a precision tool designed to verify external thread diameters quickly and reliably. Its Go-side design provides a clear pass/fail indication, helping inspectors and machinists confirm parts meet threading specifications at a glance. Designed for right-hand threads, it fits common production workflows and reduces ambiguity during acceptance testing.

Crafted from hardened steel for exceptional durability, the Unified Go gauge resists wear in demanding shop environments. The 2A class tolerance and the 2 x 12 configuration ensure consistent measurements across parts, while the compact, easy-to-handle ring shape speeds up setup and testing without removing the gauge from the work area.

• Direct Go/No-Go verification: Quickly determine if external threads meet the required diameter and tolerance, enabling fast pass/fail decisions without guesswork.
• Rugged hardened steel construction: Built to withstand daily use in busy shops, resisting wear and maintaining accuracy over time.
• Two-ring configuration for broad coverage (2 x 12): Includes two Go rings in a compact form to cover common external thread sizes, simplifying setup and testing.

This gauge helps streamline inspections, accelerate workflows, and improve the reliability of threaded components across manufacturing, maintenance, and quality control environments. With its sturdy construction and straightforward pass/fail feedback, you’ll reduce rework, shorten setup times, and achieve repeatable results that your team can trust.
