The JBO Thread Plug Gauge is a precision tool designed for fast, reliable testing of trapezoidal thread holes. Built for right-hand trapezoidal threads in 7H tolerance with a Tr. 30 x 6 size, it provides clear go/no-go indications that verify compliance with standard thread specifications. It's well suited for manufacturing, automotive, and aerospace environments where quick, accurate quality checks matter.
Use this gauge to confirm that threaded holes will properly accept mating parts, catch out-of-tolerance threads early in production, and streamline inspection workflows. The go/no-go design delivers immediate, easy-to-interpret results, helping teams make confident decisions and keep assemblies running smoothly.
