A self-boring fastener comprising an elongated cylindrical element which intersects a driving means, said cylindrical element having a knife edge means axially projecting from the periphery of the extreme end thereof so as to extend beyond said end, and a thin knife edge element continuously, helically positioned about the outer periphery of said cylindrical element, said knife thread extending outwardly laterally from the outer periphery of said cylindrical element, said cylindrical element having an axial hole extending inwardly from the extreme end thereof so as to form an internal cavity in said cylindrical element. The method of fastening rubber, wood and other non-metallic materials either together or to base materials without the necessity of preformed bores or embedded metal mating parts and without incuring the problems of misalignment by use of the self-boring fastener.
