The JBO Thread Plug Gauge is a precision Go-No/Go inspection tool designed to verify UNF internal threads in holes and assemblies. Sized for 7/8 x 14 right-hand threads with a 3B class tolerance, it provides a reliable reference for manufacturers, automotive shops, and aerospace maintenance teams to confirm threaded holes conform to Unified thread standards. With meticulous design and precise dimensions, this gauge enables fast go/no-go checks and clear indications of conforming versus non-conforming threads, helping speed inspections while maintaining accuracy.

• Go/No-Go quick verification: Fast go/no-go checks give immediate pass/fail indications for threaded holes, speeding quality control and reducing rework.
• UNF 7/8 x 14 Right-Hand, 3B class alignment: Specifically tuned for UNF internal threads at 7/8 x 14 with right-hand orientation and 3B tolerance, ensuring measurements align with standard components.
• Built for reliability in demanding environments: Designed for daily shop-floor use in manufacturing, automotive, and aerospace settings, providing repeatable results across operators and shifts.

Using the JBO Thread Plug Gauge helps streamline thread inspection, reduce guesswork, and ensure proper fitment across assemblies. The reliable go/no-go verification supports faster setup, higher first-pass yields, and consistent quality throughout production runs.
