Abstract
A male fastener element extends integrally from a planar base and includes a primary engagement hook and a secondary engagement structure (e.g., a hook). The primary engagement hook has a stem portion that is integrally molded with the planar base and that extends from the planar base to a distal end. The primary engagement hook also has an overhang portion that extends from the distal end of the stem portion and that has an underside surface overhanging an open volume for receiving loops. The secondary engagement structure, which is shorter than the primary engagement hook, is disposed immediately adjacent the primary engagement hook and extends from a side surface of the primary engagement hook. The secondary engagement structure extends from the base to a distal end that is disposed, in side view, below the underside surface of the overhang portion of the primary engagement hook.
