The JBO Thread Ring Gauge (GO) for UNJC, Right Hand, 3B, 3/8 x 16, is a precision Go gauge designed to verify external thread diameters quickly and reliably. Built for inspectors, machinists, and quality teams, it helps you confirm that threaded components meet the exact size and fit requirements of UNJC 3B right‑hand threads.

• Precise GO verification for UNJC 3B threads: Quickly confirms whether external threads meet the GO limit for 3/8 x 16, speeding quality checks and reducing guesswork.
• Rugged, wear‑resistant construction: Crafted from hardened steel to resist wear and maintain accurate tolerances in busy workshops and demanding environments.
• Ergonomic, easy‑to‑handle design: Knurled outer edge provides a secure grip and easy handling, even with gloves or greasy hands, helping you set up and read results with confidence.

Using this gauge in your inspection routine helps streamline workflows, minimize rework, and ensure every threaded connector or fastener meets the exact UNJC 3B specification. The combination of precise GO dimensions and rugged construction translates into consistent results, higher first‑pass yield, and greater confidence in your assemblies.
