ABSTRACT:
An improved fastening clip of the U- or C-shaped type has a thread engaging hole in the axially opposed clip wall with a novel hole form. The perimeter surface of the hole includes a cooperating conical rim and pair of strengthening corrugations that work together to lead the fastener tip into the hole, as well as to strengthen and stiffen the surface. The corrugations also provide thread engaging bight portions close to the plane of the axially opposed clip wall, providing added fastening security with a relatively short fastener.
