Abstract
A plastic surface fastener whose surface fastener members can be engaged by a small force includes two surface fastener members each having a plastic base and multiple projecting members having identically sized engagement heads and standing upright on the base as arranged in a matrix of prescribed pitch. The shape of the engaging heads of both surface fastener members as viewed from the top is that obtained by cutting off segments from four sides of a circle, and selected projecting members of one surface fastener member are removed in an appropriate pattern for providing room for the projecting members of the other surface fastener member to escape when the projecting members of the one fastener member are forced into spaces enclosed by the projecting members of the other fastener member.
