1. A fastener having an insertion axis, the fastener being configured to be inserted into an aperture in a structure along
the insertion axis, the fastener comprising:
a U-shaped body having a pair of spaced apart legs and a pair of laterally extending flange members, each of the flange members
being coupled to an associated one of the legs, the legs being coupled to one another at an end opposite the flange members;
a plurality of teeth coupled to the U-shaped body, each tooth extending inwardly away from an associated one of the legs toward
the insertion axis and away from the flange members;
first and second wing members, each of the first and second wing members having a warped planar shape that includes a portion
that is twisted, the warped planar shape with a first end that is coupled to the U-shaped body and a second free end opposite
the first end, the second end terminating at a distal edge surface, the distal edge surface being sloped relative to the flange
members in a vertical direction that is generally parallel to the insertion axis so that a first lateral side of the distal
edge surface is relatively closer to the flange in a vertical direction than a second opposite lateral side of the distal
edge surface; and
wherein the distal edge surface extends in a helical manner between the first and second lateral sides.
