The JBO Thread Plug Gauge is a UNS Go-No-Go gauge designed to verify threaded holes and components to Unified thread standards. This right-hand gauge, sized at 1 3/16 x 12 with 2B tolerance, is built for precision use in manufacturing, automotive, and aerospace applications, as well as maintenance and quality control environments.

• Go/No-Go Quick Checks: Instantly determine whether a threaded hole or plug meets the UNS specification, helping you identify conforming and non-conforming parts without guesswork and with faster turnaround times.
• Right-Hand UNS Threading Size 1 3/16 x 12 (2B): Precisely matched to the specified thread form and tolerance, ensuring accurate, repeatable inspections for critical assemblies and assemblies where correct thread engagement is essential.
• Durable, Ergonomic Design: Knurled grip for secure handling, color-coded ends for fast identification, and a robust construction that stands up to daily use in busy workshops and inspection bays.

Designed to integrate seamlessly into any quality workflow, the JBO Thread Plug Gauge helps you validate thread performance quickly, reduce rework, and support consistent results across teams. Its clear go/no-go feedback streamlines setup and inspection, so you can maintain high confidence in threaded assemblies from first article through production lots.
