Abstract:
A new and improved toggle-bolt type fastener has pocket structure effectively incorporated therein so as to accommodate extra-long threaded activation screws or bolt fasteners in a coaxial manner within the toggle-bolt type fastener. Alternatively, structure has been incorporated within the toggle-bolt type fastener which effectively accommodates extra-long threaded activation screws or bolt fasteners by causing the same to be slightly deflected from their coaxial disposition within the toggle-bolt type fastener so as to permit the same to bypass the stab point of the toggle-bolt type fastener. Still further, additional structure has also been incorporated within the toggle-bolt type fastener for ensuring the fact that when the nut member is moved from its first or original, axially oriented, inoperative or non-deployed position, to its second, transversely oriented, operative or deployed position, the nut member will in fact be disposed substantially perpendicular to the longitudinal axis of the toggle-bolt type fastener so as to, in turn, ensure the proper threaded engagement thereby by the threaded activation screw or bolt fastener.
Abstract:
A threaded screw fastener has a point (5), a shank (4) and a head (2). The point is a ballistic point. The shank comprises a linear travel area (6), preferably unthreaded, adjacent to the point and a threaded area (13) between the linear travel area and the head. The head is a bugle head formed with a Phillips-style recess configured to receive a driver or driving bit. The fastener is configured fasten a surface material to a substrate material and to be linearly driven into the materials before rotation of the fastener is required, thus reducing the number of rotations required to drive the fastener. The fastener is particularly suited to be used with powered driving tools that utilize both linear and rotating driving means.
Abstract:
A self-drilling anchor (110) for use in a friable material comprises a body (112)having an axis, a flanged rear end(114), a drilling front end (170)and a generally cylindrical portion therebetween having an outer surface with a thread (146) disposed thereon, wherein the body forks, beginning at a predetermined distance from the flanged rear end, into a first leg and a second leg, the first leg extending forwardly into a drilling tip and having a generally rearward facing shoulder angled obtusely outwardly with respect to the axis, wherein the body has an axial bore (132) for receiving an elongate fastener, the axial bore extending substantially through the flanged end and the generally cylindrical portion and leading to the generally rearward facing shoulder, wherein the anchor has a drilling mode wherein the second leg nests behind the generally rearward facing shoulder of the first leg, and an anchoring mode wherein the legs are pivoted apart from one another.
