The JBO Thread Ring Gauge (GO) for UNEF right-hand threads is a precision go gauge designed to verify external thread diameters quickly and reliably across manufacturing, inspection, and quality control environments.

Designed for engineers, buyers, tradespeople, hobbyists, and technicians, it confirms that components conform to UNEF 1 5/16 x 18 standards, helping you pass inspections on the spot.

• Go gauge for UNEF right-hand 2A threads: Quickly confirm that external threads match the exact 1 5/16 x 18 UNEF size and tolerance class, enabling fast, on-the-shop-floor pass/fail decisions.
• Hardened steel construction: Built for durability and wear resistance in busy workshops, delivering dependable performance under regular use and demanding environments.
• Precisely machined dimensions for consistent results: Carefully calibrated to standard UNEF specifications, ensuring repeatable measurements and reducing rework across production runs.

This gauge helps streamline quality control by providing clear, reliable checks of thread conformity. Its robust construction pairs with accurate dimensions to support consistent assembly fits, minimize downtime, and enhance overall measurement confidence across your team.
