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.

• Go/No-Go quick-check for fast QC: Immediate pass/fail feedback reduces inspection time and eliminates guesswork, speeding up quality control.
• Trapezoidal 7H compatibility (Right Hand): Precisely matched to trapezoidal threads with 7H tolerance, ensuring reliable measurements against standard specifications.
• Durable, ergonomic construction: Knurled grip and robust body provide secure handling and long-lasting performance in busy shop environments.

By delivering clear, immediate feedback on thread hole quality, this gauge helps speed up production, reduce rework, and ensure reliable mating with fasteners and components. Its rugged construction supports dependable performance across shifts, so you can trust measurements to stay consistent across batches and over time.
