ABSTRACT:
A nut plate retainer comprises a planar body, nut elements, and at least two orienting tabs. The tabs are formed from and extend parallel to the body. One tab has a locking element having a ramped leading edge and a cutaway trailing edge for snap engagement with an opening in a workpiece. The tabs fit into slots in the workpiece and the nut plate can be moved until the locking element snaps into place in the opening. The nut plate retainer is thereby mounted to the workpiece, and is prevented from rotation or displacement.
