ABSTRACT:
An anchoring structure for components such as a ball-stud grommet includes a head and a plurality of retention legs defining lips in spaced, confronting relationship with a surface of the head. The legs are arranged in a circle and are provided in sufficient number and in sufficiently close spaced relation that at least one leg on opposite sides engage edges of a slot for any rotational position of the fastener relative to the slot.
