Abstract

See full text

A method of forming a fastener member having a base and a plurality of headed stems arranged in columns and rows and projecting from the base. The fastener member is formed by injection molding a molten material into a base mold, sacrificial stem mold and head mold, wherein the material is solidified. After the base mold and head mold are removed, the stem mold may be destructively removed to release the fastener member.
