ABSTRACT:
An anchor for securing a threaded fastener component in a hole in a supporting panel structure, the anchor being formed of a flat sheet metal disc portion of a greater diameter than the hole and having strips attached at one end to the disc portion and extending radially inward and outward to position a tip inclined edge across the hole perimeter. The strips are cammed to be deflected inwardly as the anchor is forced into the hole with the disc portion against the front side of the supporting structure. The anchor is captured by the perimeter of the hole between the disc outer perimeter and the strip tips. The tips are captured in slotted tabs extending from the rear side of the disc portion.
