ABSTRACT:
An anchor nut device for attachment to a structure, the device defining a threaded bore for the reception therein of a corresponding member. The device includes an anchor nut which is fabricated from a first material, the nut defining the bore and a plurality of radially extending ears. A base plate is fabricated from a second material, the plate having a first and a second face, the first face cooperating with the plurality of ears. The second face of the plate defines a plurality of dimples for facilitating welding of the plate to the structure. A plurality of arms extend from the plate, such that each ear of the plurality of ears is disposed between a corresponding arm of the plurality of arms and the first face of the plate for capturing the nut relative to the plate. Also, a stop extends from the anchor nut, the stop being disposed between adjacent ears for controlling rotational movement of the anchor nut relative to the plate.
