ABSTRACT:
A toggle fastener which eliminates the need for time-consuming manipulation of a fastener nut comprises a bolt with a head and a stop collar adjacent the bolt head, a wing toggle threaded onto the free end of the bolt, and a spring which extends from the stop collar to a washer. The washer may be flat or a self-centering conically shaped washer. The invention permits the toggle and toggle fastener to be inserted into an aperture in a panel and to then be automatically secured to the wall with an effective firestop provided by the effect of the spring urging the washer into firm contact with the panel.
