Abstract
A compression indentation fastener device is described comprising a shank and a head. The head extends outwardly from an end of 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 an exposed area extending between the shank and the head periphery. The anterior side includes a relief portion in the form of a depression. The relief portion is open at the anterior side of the head such that the relief portion receives a volume of substrate material when the exposed area of the head impacts the substrate material. The head may be integral with the shank or the head may be comprised of discrete head portions that mate with one another. Additionally, the head may be centered on the end of the shank or offset relative to the shank.
