A screw and toggle fastener in which the toggle member is formed from spring steel so as to be flexible but non-expandable. The toggle member is provided with a centrally located aperture to permit the threaded insertion of a screw member. The toggle member has a leading portion with respect to the central aperture which may be provided with a pointed leading edge to facilitate insertion through a member to which it is to be attached. A trailing portion of the toggle member is arcuately deformed out of the plane of the leading portion by an amount which permits pivotal movement of the toggle member with respect to the axis of the screw member so that it forms a bridging contact with the threads of the screw member when the toggle member is at right angles to the screw member after passing through the members being fastened together.
