Patent number: 5842822Abstract: The new fastener has a shank which is resiliently compressible along an axis perpendicular to the shank push-in axis and has teeth protruding from the shank along the axis of resilient compressibility. The teeth are inclined in the push-in direction and in the pull-out direction. When the shank is pushed into an existing screw hole, then inclines of teeth just past the far side of the screw hole are increased to resist motion in the pull-out direction so that the shank is secured in the screw hole and so that the fastener can be pulled out without damage. The shank is configured to increase the compressibility and to increase the elastic force opposing compression. The shank can be a monolithic part of a first structure fastened to a second structure.Type: GrantFiled: May 16, 1997Date of Patent: December 1, 1998Assignee: Everett Industries IncInventors: Gerald W.

Patent number: 5244326Abstract: A fastener assembly including a first fastener member adapted to be inserted into a first structural component. The first fastener member includes a head portion and a generally cylindrical shank portion extending from the head portion. The fastener assembly also includes a second fastener member having a head portion and a shank portion extending therefrom. The first and second fastener members include respective internally and externally threaded portions that interengage to secure the fastener members together. One of the fastener members is provided with anti-rotation structure that prevents rotational movement of the fastener members with respect to the structural components, while permitting non-destructive axial removal of the fastener members from the structural components. In a preferred embodiment, the anti-rotational structure is provided as a plurality of longitudinal ridges disposed on an outer surface of the shank portion of one of the fastener members.Type: GrantFiled: May 19, 1992Date of Patent: September 14, 1993Inventor: Arne Henriksen

Patent number: 5190424Abstract: Disclosed is a stud bolt having nonsymmetrical screw threads projecting from the shank thereof, wherein each screw thread of the stud bolt has an inwardly concave curved flank and an outwardly convex curved flank. With this arrangement, the load required to fit a resin clip over the stud bolt can be lowered below that needed for a conventional stud bolt while maintaining the load required to remove the clip equal to or more than that for the conventional bolt. Thus, this stud bolt allows a resin clip to be easily fitted over the bolt.Type: GrantFiled: December 4, 1991Date of Patent: March 2, 1993Assignee: K.K.
