ABSTRACT:
A novel attachment device is provided which can be used to secure two members together, such as a shelf and a support column, with a screw and nut and which does not require the use of a wrench to keep the nut from rotating during tightening of the screw with a screwdriver. A sheet metal shelf has a depending flange with a hole in a deformable region of sheet metal between two parallel vertical slots near the corner of the shelf. A shelf support column has a vertical U-shaped channel with a hole therein. To connect a shelf to a support column, the deformable region of the shelf flange is placed across the opening of the U-shaped channel in the support column with the holes in the flange and support column in alignment and then a screw is inserted therethrough. A nut is threadingly engaged on the screw to bear against one side of the deformable region of the shelf flange and to deform the region into the U-shaped channel of the support column. The nut seats within the deformed region and is prevented from rotating as the screw is tightened.
