A molded area fastener product, such as a self-engaging fastener, has a strip-form base of resin with a broad surface from which an array of discrete fastener elements extends. The fastener elements each include a molded stem extending from the broad surface of the base to a curved head that extends toward a front side of the fastener element, forms a crook and ends in a distal tip. In some examples the curved head protrudes beyond the stem on the back side of the fastener element to form an overhang defined by an overhang surface of the head directed toward the base, and the crook is defined in part by an underside head surface that overhangs a lower portion of the stem. In some examples the fastener elements are arranged to provide a high distension overlap when mated with an identical fastener product.
