ABSTRACT:
A drain plug has an interior cylindrical component with exterior screw threads adapted to be threadedly secured with respect to a threaded aperture in a crank case. The drain plug also has an enlarged exterior head with an external periphery. The drain plug is fabricated of steel. An attachment is positionable over the periphery of the head. The attachment is of a length essentially equal to the length of the head of the drain plug. The attachment has an internal periphery of a configuration adapted to be slidably received over the periphery of the drain plug. The attachment has an external periphery in a configuration. The attachment is fabricated of a permanently magnetized material with a north pole adjacent one end and a south pole adjacent the opposite end whereby the magnetized nature of the attachment will magnetize the head of the drain plug as well as its cylindrical component to attract metal particles.
