Patent ID: 7275903

Claim:
In combination, an apparatus for installing a fastener into a hole within a structure, comprising: a fastener including an enlarged protruding head positioned at a proximal end of the fastener and substantially centered about a longitudinal axis of the fastener; a substantially cylindrical shoulder portion positioned adjacent to and extending distally from the head and substantially centered about the longitudinal axis, the shoulder portion having a first diameter; a lubricant coating composition on a surface of the shoulder portion; a threaded portion positioned adjacent to and extending distally from the shoulder portion and substantially centered about the longitudinal axis, the threaded portion including a male thread for receiving a female threaded device and having a second diameter smaller than the first diameter of the shoulder portion; an aperture positioned on a distal face of the fastener and substantially centered about the longitudinal axis, the aperture substantially defining a parabaloid and extending proximally into the fastener such that a diameter of the aperture decreases in a proximal direction; and a tapered pin having a substantially parabolic shape having a circular cross section corresponding to the shape of the aperture adapted to be inserted in said aperture with a force to prevent spinning of the fastener when said female threaded device is received on said threaded portion.
