Abstract
In a molded surface fastener, a hook structure has on at least one surface of a stem an upright reinforcing rib extending from the base of the stem to part of a hook-shape engaging portion. The reinforcing rib projects upwardly with respect to the rear surface of the hook-shape engaging portion and terminates in an apex whose height is smaller than the height of the apex of the hook-shape engaging portion and greater than the height of the line tangential to the hook-shape engaging portion at the tip and substantially parallel to the upper surface of the substrate sheet.
