The JBO Thread Ring Gauge (GO) for UNF - Right Hand - 3A - 7/16 x 20 is a precision measuring tool designed to verify external thread diameters quickly and reliably. It serves machinists, quality inspectors, and assembly teams who need confident, standards-compliant threading checks across a range of industries.

Crafted from hardened steel, this GO gauge delivers exceptional durability and wear resistance for demanding shop environments. Its straightforward GO design makes it easy to identify properly conforming threaded components, supporting efficient quality control and repeatable results.

• Exact UNF 7/16 x 20 GO verification: Provides precise go-angle reference for right-hand threads, helping you quickly pass or flag parts to standard without ambiguity.
• Hardened steel construction: Built to endure daily use, resist wear, and maintain accurate measurements over many cycles in busy workshops.
• User-friendly conformance check: Intuitive design enables fast inspections, reduces handling time, and supports consistent quality across production runs.

Using the gauge, you can streamline threaded-part inspections, improve consistency across batches, and minimize rework. The rugged build supports long service life in active environments, while clear, decisive GO feedback speeds up production and quality assurance workflows.
