The JBO Thread Plug Gauge – UNEF Go-No/Go, Right Hand, 2B, 3/4 x 20 is a precision tool designed to quickly verify UNEF threaded holes with the exact right-hand 3/4 x 20 threads. It’s a practical choice for manufacturers, automotive shops, and aerospace maintenance teams that rely on fast, reliable thread checks to keep production moving.

With its go/no-go design, you can instantly determine whether a hole meets spec, reducing inspection time and preventing misfits in critical assemblies. This gauge supports consistent thread quality across production, assembly, and repair tasks.

• Go/No-Go conformance at a glance: Instantly confirms whether a hole accepts the 3/4 x 20 UNEF thread, speeding inspections and reducing guesswork.
• 2B-grade UNEF 3/4 x 20, right-hand sizing: Engineered to exact UNEF dimensions with right-hand threading, delivering reliable go and no-go results for proper thread engagement and assembly fit.
• Durable, easy-to-handle construction: Features a textured knurled grip and robust ends designed for repeated use in busy workshop environments, minimizing downtime due to tool wear.

Using the JBO Thread Plug Gauge helps streamline your QC workflow, reduces downtime, and improves overall threading reliability across production, maintenance, and assembly tasks. By confirming threads quickly and accurately, it supports better part quality, safer fits, and consistent results from job to job.
