1/2-Inch Drive Spark Plug Socket with Magnet

Brief Overview

This is a professional-grade spark plug socket engineered for efficient engine maintenance work. The 1/2-inch square drive design integrates seamlessly with standard ratchets and torque wrenches, while the embedded magnet secures spark plugs during installation and removal—eliminating fumbling and reducing dropped components on the job. Available in three critical sizes (16mm, 18mm, 21mm) to cover a wide range of automotive applications.

If your customers work with lighter-duty pneumatic systems or prefer 3/8-inch drive tools, consider also stocking compact 3/8-inch spark plug sockets for complete workshop coverage.
