Abstract

Fastening devices of this invention comprise a screw and a spacer element. The spacer element can be cylindrical in shape and includes a central opening extending between opposite axial surfaces. One or more grooves are disposed within and extend diametrically along at least one axial spacer surface. The groove is adapted to accommodate a wire section of a wire lath. The screw includes a head at one axial end positioned adjacent the spacer groove, and a tip at an opposite axial end for penetrating and engaging a surface of an adjacent structure. The head includes an enlarged diameter section that extends radially outwardly therefrom a sufficient distance to cover at least a portion of the groove when the mounting means is disposed within the central opening. The fastening device is used to attach a wire lath to another surface by placing a wire section of the wire lath within the spacer groove, and driving the mounting means into the other surface. During the driving step, the spacer element is interposed between the other surface and the mounting means enlarged diameter section, and the wire section is secured between the groove and the enlarged diameter section to permanently attach the wire lath to the other surface.
