A toggle bolt fastener assembly comprises a tubular toggle housing body defining a longitudinal axis and within which a nut member is guidably moved in a translational manner, the nut member always being disposed coaxially with respect to the longitudinal axis of the toggle housing body. A pair of toggle wing members are pivotally mounted upon the nut member, and the nut member includes lug structure for cooperating with a first pair of longitudinal slots formed within first opposite side wall portions of the toggle housing body so as to prevent relative rotation of the nut member with respect to the toggle housing body. A second pair of longitudinal slots are formed within second opposite side wall portions of the toggle housing body so as to permit the toggle wing members to be movable therethrough between radially contracted and radially expanded positions. A pair of compression sleeve members are also provided upon the toggle housing body for forcing the toggle wing members to their radially contracted positions when the nut member is disposed at a first translational position with respect to the toggle housing body, whereas when the nut member is disposed at a second translational position with respect to the toggle housing body at which the toggle wing members are disengaged from the compression sleeve members, the toggle wing members attain their radially expanded positions.
