Abstract

A self-drilling screw capable of engaging with a metal plate having plywood thereon is provided. The self-drilling screw has only one wing or two wings asymmetrically formed on the screw. Such design can prevent the cutting edges of the screw from being stripped out as a result of heat resulting from that the cutting edges rub against the metal plate during drilling. The plywood on the metal plate is also not to be ignited.
