ABSTRACT:
A button attaching fastener consisting of a button cap and an attachment plug. The button cap has centrally in its rear surface a socket, and the attachment plug has on one end a flange fitted in the socket with a clench portion provided along an outer periphery of the socket clenched over the flange through its substantially entire surface. The clench portion has on its outer surface a plurality of rotation-preventing projections extending radially outwardly from the base of the flange. The rotation-preventing projections serve to prevent the fastener from rotating on a piece of fabric, as of clothing, and also to increase the pulling strength of the attachment plug.
