The JBO Thread Plug Gauge is a trapezoidal go-no-go gauge designed for right-handed internal threads. With a 7H tolerance and Tr. 22 x 5 size, it provides precise, reliable checks of trapezoidal hole threads in manufacturing, automotive, and aerospace applications, helping ensure parts meet threading standards.

This go/no-go tool enables quick conformance checks so inspectors can rapidly identify both compliant and out-of-tolerance holes, speeding up quality control and reducing rework.

• Go/No-Go design for fast, conclusive checks: Quickly determine if a hole accepts the thread within tolerance, reducing guesswork and downtime during inspection and assembly.
• Trapezoidal Right-Hand precision (7H, Tr. 22 x 5): Specifically engineered to match internal trapezoidal threads, ensuring accurate acceptance testing and reliable results in critical applications.
• Meticulous design with precise dimensions: Delivers repeatable measurements and consistent results across production runs, supporting quality control in manufacturing, automotive, and aerospace.

Together, the JBO Thread Plug Gauge streamlines threaded hole verification, helping you speed up inspections, minimize rework, and ensure reliable assemblies. Its focused trapezoidal threading specification and go/no-go capability give your team confidence in every measurement, making it a trusted addition to any quality lab or shop floor.
