Abstract
A self-drilling fastener includes an elongated shank region having first and second ends, a head at the first end and a drill point at the second end. Included in the shank region is a root having helical threads extending therefrom with a predetermined thread density. The threads are configured to extend onto the drill point, which point extends from the root, and has a conical point with a rounded tip and a flat side. The flat side defines a pair of drilling edges.
