ABSTRACT:
In a molded surface fastener, a hook has vertical multi-step reinforcing ribs on opposite side surfaces of a stem, and it is therefore possible to make the hook-shape engaging portion adequately soft and to increase the rate of engagement with loops. Further, since each reinforcing rib extends to the curve of the hook-shape engaging portion, it is possible to secure a predetermined degree of engaging force, despite the thin and soft hook-shape engaging portion, unlike the simple reinforcing ribs of the conventional art.
