The JBO Thread Ring Gauge (GO) - BSW - Right Hand - Medium Class - 5/16 x 18 is a precise external thread verification tool designed for quality assurance across manufacturing, machining, and repair applications. It helps engineers, inspectors, and shop personnel quickly determine whether threaded components meet the exact outer diameter and thread form requirements for reliable assembly.

Crafted from hardened steel, this GO gauge offers exceptional durability and wear resistance in demanding environments. Its straightforward ring design makes it easy to slip over the tested thread to confirm conformance, supporting efficient quality control and consistent results on the shop floor.

• Precise GO measurement for quick conformance: Designed to the exact 5/16 x 18 BSW right-hand Go size, enabling fast, reliable pass/fail checks that streamline inspection and assembly workflows.
• Hardened steel construction for durability: Built to endure daily use in busy workshops, resisting wear and corrosion so accuracy is preserved over time and through many cycles of testing.
• User-friendly inspection and quick identification: The ring design provides immediate, clear feedback, allowing operators to rapidly identify parts that conform and reduce rework or downtime.

Using the JBO Thread Ring Gauge (GO) ensures consistent thread quality across batches, supports accurate part interchangeability, and integrates smoothly into standard inspection routines. Its robust construction and easy handling help you make confident, on-the-spot decisions that keep production moving and quality uncompromised.
