ABSTRACT:
This invention is a wall fastener to join abutting surfaces such as affixing a bracket to a wall. The L-shape arms of the fastener are attached with hinges to a shell or to a slidable nut enclosed in a shell which is inserted in a preformed hole or aperture in the wall. The fastener with arms attached to the slidable nut is adjustable for use with walls of varying widths. A screw holding the object to be attached is inserted in the shell and threaded through the nut (FIG. 4). The screw then engages the arms of the fastener and forces them to pivot into a clamping position (FIG. 5). The screw is turned until the arms are clamped against the wall (FIG. 6). The fastener with the arms attached to the shell is similar in operation to the adjustable fastener except its use is for walls or surfaces of the same width as the device.
