Abstract: An outdoor display includes a net formed of intersecting cables and a number of pixel display units disposed on the net at the intersection of a pair of cables. Each pixel unit includes a number of different colored LEDs. The LEDs of the pixel units forming the display are selectively activated to form a still image or moving video images. The net display can be attached to, supported by or between existing structures.

Abstract: A corrosion resistant screw type fastener has a carbon steel threaded shank with a die cast zinc or aluminum head, and a reformable plastic washer positioned about the shank and partly received within the head. The shank has a retaining portion having a polygonical configuration and a cylindrical portion between the retaining portion and the threads. The retaining portion has a larger cross-sectional configuration than the cylindrical portion for preventing axial movement between the head and the shank. An annular recess is formed between the head and part of the cylindrical portion for receiving the washer which is thicker than the depth of the recess. When the fastener is threaded into the work the heat and pressure generated reform the washer to completely fill the recess and provide an effective seal against corrosive elements.
