A toggle bolt fastener assembly comprises a tubular toggle housing body within which a coaxially disposed nut member is guidably moved in a translational manner. The nut member includes lug structure for preventing relative rotation or pivotal movement of the nut member with respect to the toggle housing body, and a pair of toggle wing members are pivotally mounted upon the nut member 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, or for permitting the toggle wing members to move to their radially expanded positions depending upon the disposition of the nut member within the toggle housing body.
