The JBO Thread Plug Gauge is a right-hand, medium-class go/no-go gauge sized 1 1/4 x 7, built to verify threaded holes and mating parts with confidence. It’s an essential tool for manufacturers, automotive shops, and aerospace workshops that rely on accurate thread fit and consistent quality.

With meticulous design and precise dimensions, it enables fast, reliable inspection of threads in line with Unified thread standards and specifications. The go/no-go form makes it easy to distinguish conforming from non-conforming threads at a glance, aiding quick decisions and reducing rework.

• Go/No-Go quick conformance check: Instant pass/fail readings for 1 1/4 x 7 BSW right-hand threads, speeding inspections and reducing guesswork.
• Standards-aligned precision: Precise dimensions ensure threaded holes meet Unified thread standards and specifications for reliable mating and performance.
• Right-Hand, Medium Class compatibility: Designed for common right-hand threads and medium-class tolerances, delivering consistent, repeatable results across typical parts and assemblies.

This gauge helps you streamline inspection workflows, minimize downtime, and improve the reliability of threaded connections. By delivering clear, immediate feedback on thread quality, it supports better quality control, fewer defects, and smoother assembly processes for engineers, buyers, and shop floor teams alike.
