The OTC 5911A magnetically attaches to pre-loosened oil pan drain plugs so you can remove them without dropping and avoid getting burned with hot oil. The patented design provides universal application to hex heads. A flexible shaft can be used in virtually any location and still turn the plug as desired. An added feature of the 5911A is a removable magnetic end with 1/4" square drive. When removed, the drain plug pro becomes a flexible-shaft 1/4" bit driver. Use for sockets and bit holders to get into hard-to-reach places including under dashboards and in engine bays to remove bolts once loosened. Designed for repetitive daily use with a Lifetime warranty.
