ABSTRACT:
A bushing cooperates with a bolt and a winged toggle member to form a toggle bolt assembly. The bushing has a maximum cross-sectional dimension substantially equal to the diameter of the hole in the wall or other support member to which the toggle bolt assembly is to fasten an object and an inside diameter permitting passage of the bolt therethrough. To fasten an object to a wall, the bolt is passed through an opening in the object and through the bushing and threadedly engaged in the toggle member. The toggle member wings are folded, and the toggle member is passed through the hole in the wall until the wings open. The bushing is inserted into the hole and held in place while the bolt is pulled outward until the opened toggle wings abut the inner surface of the wall, inhibiting rotation of the toggle member as the bolt is rotated. The bolt is then threadedly tightened in the toggle member, drawing the object and the wings into further engagement with the opposite surfaces of the wall.
