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 maybe centered or offset relative to the shank.

Abstract: An improved fastener for securing a first building component to a second building component is provided. The fastener includes a head, a shank, and a tip. The shank is connected to the head and extends along a longitudinal axis to the tip. The shank includes an upper shank portion, a lower shank portion, and a transition zone. The upper shank portion is located adjacent to the head. The lower shank portion is spaced from the upper shank portion and is located adjacent to the tip. The transition zone is positioned longitudinally between the upper shank portion and the lower shank portion. The transition zone is longitudinally spaced from the head by a pre-determined distance. The pre-determined distance is associated with a thickness of the first building component such that the transition zone is aligned with a joint between the first and second building components.

Abstract: An anchor bolt device for securing a structural member to a concrete foundation is described. The anchor bolt device includes a first anchor bolt, which has an enlarged portion, a shank portion, and a tail portion. The enlarged portion extends from a first end of the first anchor bolt and has an enlarged portion cross-section. The tail portion extends from a second end of the first anchor bolt and has a tail portion cross-section. The shank portion is disposed between the enlarged portion and the tail portion and has a shank portion cross-section that is smaller than the enlarged portion cross-section. A first coupling is disposed at the first end of the first anchor bolt for securing the first anchor bolt to the structural member. A second anchor bolt may be coupled to the second end of first anchor bolt at a second coupling.

A second anchor bolt may be coupled to the second end of first anchor bolt at a second coupling.

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.
