Abstract
The embodiment of the invention disclosed herein is directed to a fastener structure which has a pair of spaced apart prongs extending from a head portion thereof for insertion through aperture means formed in a thin panel. The prongs extend from a head portion which is to be positioned on one side of the panel and have shoulder portions extending transversely thereof to engage the other side of the panel after the fastener is inserted into the panel. The prongs have a neck portion formed between the head portion and the shoulder portion to be in registry with the thickness of the panel after the fastener is in place. The neck portion has a varying cross-section, when viewed in a plane parallel to the panel, with a thin portion at one end of the neck and a thick portion at the other end of the neck for providing different degrees of flexure therealong. The prongs, as they are inserted through the panel, will flex and twist toward one another with the greatest degree of flexure taking place at the thin portions of the necks.
