The JBO Thread Plug Gauge is a precision go-no/go inspection tool designed for BSF threads. It enables quick, reliable checks of threaded holes to verify compliance with Unified thread standards. With its exact Go/No-Go design, it helps ensure proper fitment and smooth assembly across repair, manufacturing, and maintenance tasks.

Designed for right-hand threads in the Medium Class tolerance and sized at 11/16 x 14, this gauge is ideal for manufacturing, automotive, aerospace, and shop floor QA teams. It provides a straightforward pass/fail assessment that reduces inspection time and minimizes misfits in critical assemblies.

• Go/No-Go verification: Quickly determine whether BSF threads in holes conform to the standard by presenting a clear pass or fail reading, speeding up inspections and reducing rework.
• Precise, standards-aligned dimensions: Manufactured to align with Unified thread specifications, ensuring accurate checks and consistent results across parts and batches.
• Right-hand, Medium Class 11/16 x 14 fit: Specifically sized for common BSF right-hand threads, delivering reliable compatibility with typical components and assemblies.

Using the JBO Thread Plug Gauge streamlines quality control by providing fast, repeatable thread verification. It helps you catch non-conforming holes before they become costly failures, reduces downtime, and supports consistent performance in assemblies that rely on precise BSF threads. The gauge's precise design and industry-aligned sizing give your team confidence during inspections, enabling smoother workflow and higher first-pass acceptance rates.
