ABSTRACT:
A fastener having an integral head and shank which are formed from a strip of sheet metal of indeterminate length in which the head is formed by slitting and compressing a section from one edge of the sheet material to provide a split head having two substantially similar halves with at least a portion of each half being generally perpendicular to the shank and with at least a portion of the head being thicker than one-half of the thickness of the sheet material and in which the forming of the head causes a slot in the upper surface of the head which is less than one-third the thickness of the sheet material.
