The JBO Thread Ring Gauge (GO) for BSW right-hand threads is a precision tool designed to verify external thread diameters with confidence. Built for engineers, machinists, inspectors, and workshop teams, it confirms whether a component’s major diameter meets the exact GO tolerance required by BSW standards. Crafted from hardened steel, this gauge delivers durable, long-lasting performance in demanding environments.

• Fast GO verification: Quickly confirms that the external thread major diameter meets the BSW GO tolerance, enabling faster inspection and safer pass/fail decisions.
• Durable hardened steel construction: Built to endure busy workshops, resisting wear and maintaining precise measurements through repeated use.
• Size-specific BSW Right-Hand, 1 3/8 x 6, Medium Class: Designed for exact compatibility with this standard, reducing guesswork and delivering reliable, repeatable results.

Used in quality control and assembly workflows, this GO gauge helps you validate thread conformity with minimal downtime, supporting consistent thread fits across parts and batches. Its rugged build and straightforward operation give teams greater confidence in inspection outcomes and faster decision-making during production and maintenance tasks.
