Abstract:
1. An anchoring assembly adapted to secure a screw fastener in a material engaging position at a pre-drilled hole in a concrete, brick or masonry building material, said anchoring assembly comprising: (a) an elongated screw including a torque driven head and a threaded portion adapted to advance into building materials by means of torque applied to said head, (b) wherein said threaded portion includes a cylindrical shank and laterally extending helical cutting threads with an overall outside diameter less than the nominal diameter of the pre-drilled hole so as to provide an elongated engagement cavity between said screw and said pre-drilled hole, (c) wherein said engagement cavity is radially offset from the axis of said screw to one side of said pre-drilled hole and extends axially along a substantial portion of the depth of the said pre-drilled hole; and (d) an elongated anchor strip extending longitudinally generally parallel to and axially adjacent to said screw and including an elongated malleable and non-resilient anchor member adapted to frictionally engage both said helical threads and said building material in said engagement cavity and to frictionally engage said threads to said building material radially opposite to said engagement cavity, (e) wherein said malleable anchor member has a lateral thickness greater than the lateral width of said engagement cavity.
