Abstract: A screw has a head releasably engaged by a flat blade tip in such a manner so as to prevent the flat blade tip from sliding off of the head of the screw as the flat blade up tip drives the screw. The head of the screw has a blind slot defined by a pair of walls and which extends diametrically and completely thereacross, and a blind bore extending concentrically therein. The diameter of the blind bore is less than the width of the blind slot preventing damage to, or breakage of, a drill bit used to drill the blind bore during manufacture by preventing the drill bit from hitting the pair of walls during drilling. The flat blade tip has a projection depending centrally therefrom that is coplanar with, and is a continuation of, the flat blade tip so as to allow the projection to be readily formed by merely removing material from the flat blade tip.
