  • Patent number: 6702535
    Abstract: A friction stir rivet is rotated and driven through a first fusible workpiece into an engaged second fusible workpiece, causing local portions of the first and second workpieces to plasticize. A slideable cap contacts the exposed surface of the first workpiece shortly after the process begins. The cap acts as a retaining element limiting plasticized material from escaping during the process. As the rivet is further driven into the members the cap slides up the rivet and actuates an angled stirring member to increase the stir radius around the body of the rivet. Once the rivet is driven into the first and second workpieces, rotation is stopped and the plasticized material cools and hardens around the rivet, creating a weld joining the workpieces and encompassing the rivet, which provides additional mechanical strength.

  • Patent number: 6039408
    Abstract: A break-away lug nut positioner for holding lug nuts on a race car wheel to facilitate more rapid tire changes during pit stops. The break-away lug nut positioner includes a spacer that supports a lug nut at a proper distance over a mounting hole of a race car wheel. That is, the spacer holds the lug nut so that it is adjacent to a threaded mounting stud when the wheel is held flush against the race car hub. During installation, the lug nut is driven into the spacer cavity, forcing the spacer to break into pieces. The adhesive bond between the lug nut and the spacer is weaker than the individual pieces of the spacer, which causes the spacer to separate cleanly from the lug nut, allowing the lug nut to seat properly against the wheel mounting plate. That is, the adhesive and the material and configuration of the spacer are selected so that the spacer breaks cleanly away from the lug nut, and no spacer material remains between the lug nut and the mounting plate.

To permit the bolt to turn and cause the end of the shank to advance into the void and thereby tighten the fastening, the threaded shank has coated thereon a releasable barrier layer that acts to masks surface irregularities in the shank thread and to slightly space the shank thread from the female thread. As a consequence, the female thread cast in the epoxy is functionally free of irregularities and is loosely intermeshed with the shank thread whereby the bolt can then be easily turned.

  • Patent number: 5749692
    Abstract: A fastener is formed from carbon steel wire so as to have an elongate shank defining an axis, an enlarged head formed at one end of the shank, and a generally pointed tip formed at the other end of the shank. The shank has a ringed portion formed with annular grooves defining annular rings and with helical grooves intersecting the annular grooves and defining helical ribs. The fastener is heat-treated, zinc-plated, and chromate-coated. Substantially all of the shank or of the fastener, as a whole, is further coated with a polymeric material to resist corrosion, to improve ease of driving the fastener, and to increase holding power of the fastener when driven through a wood, plywood, or plasterboard workpiece and then through a steel framing member. Substantially all of the shank or of the fastener, as a whole, may be thus coated with the polymeric material. The polymeric material softens and flows upon penetration and rehardens.

  • Patent number: 5749670
    Abstract: A method for securely joining together at least first and second structural elements without disrupting the contour or continuity of the surfaces of the structure or the structural elements is disclosed. The first structural element has a first hole having a counterbored section. The counterbored section has a recessed cavity therein, which is open to the counterbored section and has an upper wall that extends generally radially outwardly from the longitudinal axis of the first hole. The second structural element has a second hole in coaxial alignment with the first hole. A fastener, such as a bolt or stud and nut combination, is inserted into the coaxially aligned holes so that the structural elements are thereby joined and the head of the bolt or nut is recessed in the counterbored section of the first hole. A suitable castable material, e.g. aluminum, is then applied to the first hole so as to fill any remaining space in the hole, including the counterbored section and the recessed cavity.
