Abstract: A toggle bolt assembly for use with an opening in an associated wall, the toggle bolt assembly comprising a bolt of a specified diameter including a threaded diameter, a shank, and a head. The toggle member has a threaded receiving aperture and a pair of wings pivotally mounted on opposite sides of the aperture. A bolt centering spacer comprises a generally cylindrical body having a first end, a second end, a longitudinal axis, an outside diameter substantially the same as a diameter of a hole in an associated supporting surface, and an opening having a diameter substantially the same as the threaded diameter of the bolt for receiving and centering the bolt. A flange positions the bolt centering spacer along a longitudinal axis of a hole in an associated supporting surface. At least one continuous groove circumferentially extends around an outside perimeter of the cylindrical body.
