The JBO Thread Ring Gauge (NoGo) is a precision tool designed to verify external threads on components with British Standard Whitworth (BSW) right-hand threads. Sized 1 1/2 x 6 and classified as Medium class, it provides a reliable go/no-go check that helps ensure threads meet exact specifications.

Crafted for everyday use in manufacturing, automotive, and aerospace settings, this gauge supports quick, confident inspections and helps maintain consistent quality across parts and runs. The NoGo design makes nonconforming threads easy to spot, reducing the risk of incorrect fits in assemblies.

• Go/No-Go verification for quick quality checks: The no-go design delivers an immediate pass/fail indication, enabling fast sorting of compliant versus nonconforming threads and minimizing rework.
• Rugged hardened steel construction: Built to withstand daily shop use, it resists wear and corrosion and maintains accuracy over many cycles of use.
• Precisely sized for 1 1/2 x 6 BSW right-hand threads, Medium class: Provides targeted, reliable checks for the intended thread size and tolerance, ensuring consistency and easy integration with other gauging tools.

Using this gauge streamlines inspection workflows, supports accurate part fitment, and helps sustain high-quality outcomes across production, maintenance, and quality-control processes. It offers a dependable, repeatable measurement reference that you can trust from one shift to the next.
