A fastening member of the type characterized by having a base carrying on one side thereof gripping fastener hooks for mating connection with complementary gripping fastener fibrous patches. A protective cover engages the base for enclosing the hooks against leakage of molding liquid past the film onto the hooks to protect the hooks against clogging by a molding liquid when molding the fastening member into a molded article in a mold. In the improvement according to the invention, a flexible, granular ferromagnetic attachment strip is provided, and is positioned in overlying relation on top of the hooks. The attachment strip extends along the length of the fastening member within the area enclosed by the temporary thin protective film for being attracted to a magnet in the mold. The ferromagnetic attachment strip temporarily holds the fastening member by magnetic attraction in the mold during the molding process.
