Abstract
An enlarged head fastener device and method for manufacturing the same is described. The enlarged head fastener device includes a shank and a head. The head extends outwardly from the shank in a transverse plane to define a head periphery. The head has an anterior side and a posterior side. The anterior side includes a bearing surface and a convergent transition portion that reinforces the head. The convergent transition portion extends between a large end adjacent the bearing surface to a small end adjacent the shank. At least one ridge formation projects from the anterior side of the head providing additional reinforcement. The ridge formation extends continuously between an outboard end positioned on the anterior side of the head adjacent the head periphery and an inboard end positioned on the shank. The head may be centered or offset relative to the shank.
