Abstract: A toggle bolt wall stabilizer to insure a snug and proper fit of the toggle bolt to ensure dimensional stability by filling the excess wall hole required to install the toggle bolt wings through the wall surface to the inside wall surface. The toggle bolt stabilizer includes a cylindrical body plug sized in diameter to match the toggle bolt wing diameter when closed during installation and including an inside passage longitudinally to receive the bolt shaft. In a preferred embodiment, an exterior annular lip on the exterior wall side may be provided to seat against the exterior wall surface and to prevent the bolt from falling through the wall aperture. Additionally, a spacer may be utilized to extend the bolt head from the wall firmly as a seat for hanging objects.
