The JBO Thread Plug Gauge is a precision Go/No-Go inspection tool designed for quickly verifying threaded holes and fittings. It’s ideal for shops and quality teams in manufacturing, automotive, and aerospace environments, helping ensure every part meets exact thread size and tolerance without guesswork.

Designed for right-hand threads in a medium class, and sized at 9/16 x 12, this gauge delivers reliable, repeatable checks that support accurate fitment and consistent performance across production runs.

• Go/No-Go conformance checks: Quickly identify whether threads are within tolerance by comparing against the GO and NO-GO limits, speeding up inspections and reducing rework.
• Durable, easy-to-handle construction: Knurled grip and robust end fittings provide secure handling on busy workbenches and in field environments, promoting repeatable measurements.
• Specifically sized for BSW right-hand threads: Precise 9/16 x 12, medium class compatibility ensures reliable checks for common thread applications and consistent results across parts and assemblies.

Using the JBO Thread Plug Gauge streamlines quality control, helps you confirm proper thread engagement early in the assembly process, and supports faster, more accurate decision-making—leading to fewer defects and improved overall performance in your threaded components.
