The JBO Thread Plug Gauge is a precise go/no-go tool designed for professionals who inspect threaded holes. Sized for 1 1/8 x 7 BSW right-hand threads and graded to Medium class tolerance, it helps ensure every hole meets standard thread specifications quickly and reliably. Use it on parts from manufacturing lines, automotive assemblies, and aerospace components to confirm proper fitment and consistent performance.

• Two-Ended Go/No-Go Design: Provides immediate pass/fail feedback for internal threads in a single tool, speeding up inspections and reducing guesswork on the shop floor.
• Precise 1 1/8 x 7, Right-Hand, Medium Class: Engineered to exact size and tolerance, delivering repeatable conformance checks for BSW threads and minimizing rework due to misfits.
• Ergonomic, Durable Construction: Knurled grip and rugged ends deliver secure handling in busy environments and stand up to daily use in manufacturing and maintenance settings.

Using this gauge helps you verify threaded holes against standard specifications, reduce downtime from failed parts, and accelerate setup and quality control across production, automotive, and aerospace applications. It supports consistent, reliable results and gives inspectors and machinists confidence that every threaded connection will perform as intended.
