  • Patent number: 6669421
    Abstract: The present invention relates to a connecting element which comprises a bolt element with a head and a shank adjoining the latter. The head is formed from a means of engagement for a tool, which is arranged concentrically in relation to a longitudinal bolt axis, and a first eccentric disk, which is arranged eccentrically in relation to the longitudinal bolt axis. At least one second eccentric disk (22), which has a circumferential punching burr, can be pushed onto the shank by way of an eccentrically arranged push-on opening (24). According to the invention, the shank and the second eccentric disk can only be pushed onto the shank in the correct position, such that the circumferential punching burr is oriented away from the head.

  • Patent number: 6669426
    Abstract: A fastener having a head and a cylindrical shank, the shank having a first set of opposed wings extending from two opposed longitudinally extending segments and a second set of opposed wings extending from the two other opposed longitudinally extending segments. Wings in opposing segments are identical. Wings in the first set have a larger radial diameter than wings in the second set. Wings in adjacent segments are offset a distance longitudinally. There is a longitudinally extending spacing between one radial edge of each wing in the first set and one radial edge of each wing in the second set. Each of the wings in the second set has a flattened portion on a distal edge that extends to a radial edge. The fastener is particularly useful for maintaining a high ratio of disengage force to engage force over a range of aperture sizes, shapes, and panel thicknesses.

  • Patent number: 6665922
    Abstract: A fastener for installation into a workpiece which may be installed by either a swaging operation or a torquing operation. The fastener includes an enlarged protruding head which is proximal to a substantially cylindrical smooth shank portion. A threaded shank portion positioned distal to the smooth shank portion includes a male thread which is sufficiently strong to have a swage collar swaged onto it. Distal to the threaded shank portion is a pin tail portion having a surface which is configured to engage a tool. Positioned between the threaded shank portion and the pin tail portion is a breakneck groove having a lower tensile strength than any other portion of the fastener. The tensile strength of the breakneck groove is controlled such that the fastener severs within the breakneck groove when a preset range of tension is applied to the pin tail portion by the tool.

  • Patent number: 6666637
    Abstract: An internally threaded, segmented nut and conical bore for a pressure vessel are used to make removal of studs securing covers over openings through the pressure vessel wall. The segmented nut has a conical upper surface to mate with a corresponding surface of the conical bore when the stud is threaded through the internal thread of the nut and a load is applied. The segmented nut is easily replaced and the stud is easily removable due to the shape of the nut and bore. The segmented nut eliminates drilling and rethreading the bore to repair damaged threads.

  • Patent number: 6663330
    Abstract: A compression limiter formed by a roll forming process includes a substantially cylindrical body portion and a plurality of feet. A plurality of notches are stamped along a lower edge of a flat sheet of stock and bent to form the plurality of feet. The flat sheet of stock is then rolled to form the compression limiter. In the preferred embodiment, the compression limiter is formed of a high carbon steel. The plurality of feet of the compression limiter transmit the bolt load of a fastener attaching a plastic intake manifold to a component. In an alternative embodiment, an angled portion attaches each foot to the body of the compression limiter which accommodates for variations in the height of the plastic intake manifold.

  • Patent number: 6659699
    Abstract: A lockbolt includes a bolt head, a shank, a locking portion, a predetermined breaking point, and a break-away portion. The locking portion includes a knurled surface having knurling peaks between intersecting knurling grooves that extend in a direction with an axial component, e.g. spiraling helically. A sealant on two workpieces smears onto the knurled surface when the bolt is inserted in a hole therein, but does not need to be removed. A locking collar is swaged onto the locking portion to secure the workpieces between the head and the collar. The sealant is distributed as a thin layer to provide a seal and an adhesive bond between the collar and the knurled surface. Excess sealant is squeezed-out axially, without forming encapsulated pressurized sealant pockets and without hindering the swaged engagement of the locking collar onto the knurling. Then the break-away portion is broken-off at the breaking point.

  • Patent number: 6659702
    Abstract: The present invention provides a bolting structure for a magnesium alloy member, having a non-magnesium alloy and conventional member 12 disposed on the magnesium alloy member 15, the magnesium alloy member 15 being covered with an insulator 14, and a bolt 18 initially inserted through the magnesium alloy member 15 and then into the conventional member 12, thereby permitting the conventional member 12 and the magnesium alloy member 15 to be bolted together, comprising: a washer 17 disposed between a head 18a of the bolt 18 and the magnesium alloy member 15, the washer 17 having a boss 16 disposed thereon, wherein the magnesium alloy member 15 is formed with a through-hole 13 that is greater in diameter than a bolthole 19 of the washer 17. The above boss 16 and through-hole 13 eliminate a chance that the bolt 18 contacts the through-hole 13. The insulator 14 remains intact because of non-contact of the bolt 18 with the through-hole 13 so that no stray current corrosion occurs.

  • Patent number: 6644903
    Abstract: A captive fastener for press-in installation in panels has a ferrule capable of being crimped to provide a positive engagement with a screw element of the captive fastener. The ferrule has a hardness gradient such that a penetration tip of the ferrule has a hardness greater that exceeds the hardness of the panel, and an upper rim of the ferrule is deformable to limit movement of the ferrule relative to the screw element by interference. Typically, the penetration tip has a hardness greater than about Rockwell B60 to permit the press-in installation to the panel.
