Abstract
A fastener has a generally cylindrical shank and a driver at a first end of the shank. The shank has a thread having a first side and a second side opposed to the first side. The first and second sides form a compound angle between the shank and an apex where the first and second sides meet. The compound angle is formed by a body portion extending along the first and second sides from the shank to an intersection, and a crest portion extending along the first and second sides from the intersection to the apex. The first and second sides in the body portion form a body angle with respect to each other, and the first and second sides in the crest portion form a crest angle with respect to each other. The crest angle is greater than the body angle.
