The Pro Plug Socket is a durable, lightweight tool designed for easy access in tight spaces.

The socket fits 21mm (13/16") spark plugs and is compatible with a 3/8" square drive or a 17mm wrench. It includes an innovative internal plug retention system and easy-to-read laser-etched markings. A through hole allows for use as an axle-holding tool on bikes with 17mm or 24mm internal hex axles and can also accommodate a screwdriver or holding rod for added versatility.
