The JBO Thread Plug Gauge is a precision go/no-go tool designed for checking internal BSW threads in holes and housings. Built for manufacturing, automotive, and aerospace environments, it helps verify that threaded features meet the 1 1/2 x 6 right-hand, medium-class specification quickly and consistently.

With two ends for go and no-go validation, the gauge delivers immediate pass/fail feedback, helping you spot nonconforming holes without guesswork. A knurled body and color-coded end markers provide secure handling and easy orientation in busy work environments.

• Go/No-Go quick conformance: Quickly determine if the threaded hole is within tolerance, reducing inspection time and minimizing guesswork during assembly.
• BSW 1 1/2 x 6 right-hand thread accuracy: Precisely matched to the specified thread form and direction, ensuring reliable measurements across parts and batches.
• Ergonomic, durable construction: Knurled grip and color-coded ends provide secure handling and clear start/stop orientation for repeatable checks in demanding environments.

Designed to streamline quality control, the JBO Thread Plug Gauge helps you verify thread acceptance in minutes, cut rework, and maintain consistent fitment across components. Its precise sizing and durable build support long service life in fast-paced shops, while the go/no-go design delivers decisive results you can trust in critical assemblies across manufacturing, automotive, and aerospace applications.
