Anchor nuts, aka nut plates, nut plates or anchor plates, are terms used interchangeably and relate to stamped sheet metal fasteners with an internally threaded tube and a plate with two clearance holes for rivets. Initially designed and still extensively used in aerospace applications, they are today also used in automotive, motorsports, and many other industries in blind mounted panel applications where hex nuts cannot be used or an attached nut is required for ease of maintenance.
