ABSTRACT:
The invention is a connector that provides for visual recognition from remote locations and under poor visibility conditions. It may be a screw with a colored head. The screw, including the threaded shaft and the head, may be of steel, brass, plastic or any other acceptable material or combination of materials thereof. The entire or parts of the screw may be colored or plated with a colored layer or have a colored coating. Coating may include a layer of paint. For aquatic applications the paint layer is water resistant and chemical resistant and is of a color that is easily identifiable from a water surface. It may be a fluorescent paint coating. Any appropriate color or kind of paint may be used. Other coatings may be applied, such as ink coatings. The connector may have a colored cap connectable to the head of the connector. The cap may be attached following securement or may be positioned over the screw before securement. The cap may include a surface for receiving the head of a screwdriver shaft or for withstanding the impact of a hammer. The cap may be glove-fit or secured to the screw head by any attachment means. The colored cap may expose the socket on the head which receives the driver. The indicator may also be a colored disk fitted on the screw having coatings of paint or ink or epoxy and may be fluorescent. The screws may be used in pools, hot tubs, spas and whirlpools and the like. By securing grates in bottoms of pools, spas, hot tubs and whirlpools using screws having colored heads as indicators, inspectors, owners and users can immediately identify an unsecured grate from the water surface.
