ABSTRACT:
A toggle type of fastening device which includes a plate in one piece having an opening therein, the edges of the opening being engaged by a screw, the ends of the plate being bendable inwardly toward each other against spring tension to allow the plate to pass through a wall opening and being resilient so that when the plate has passed through the wall opening the ends spread out and prevent the plate from being drawn back out of the wall opening. Another feature is the provision of a rib for added strength and yet another feature is the threaded engagement of the screw with the plate at different levels. The process for manufacturing such a device includes the step of forming the opening in a piece of metal, forming a rib about the opening and then treating the formed piece to make it resilient after it has been deformed.
