ABSTRACT:
An anchor, preferably formed of metal, has at least one flat side and is adapted to be forcefully inserted axially into a complementary shaped aperture formed in an object made of a softer material than the anchor, such as plastic. The anchor is adapted to receive an attachment fastener in a central threaded opening formed in the anchor, after the anchor is forcefully seated in the aperture of the object. A plurality of angled barbs extend outwardly from the body and cut into the object to resist pullout of the anchor once seated in the object, with the flat side resisting rotation of the anchor with respect to the body. The anchor may be formed with flat corner areas which align with rounded corners of the object aperture. In the alternative, generally circular stress relief areas are formed in the corners of the aperture which align with shape square corners of the anchor. The outer dimensions of the anchor body sides are slightly less than the internal dimension of aperture but the widths of the barbs are greater than the corresponding widths of the aperture.
