Abstract
A method and apparatus for manufacturing a masonry fastener having a helical portion. A workpiece is positioned between a pair of tools mounted for relative movement. Both tools have faces defining a plurality of raised and recessed portions that extend generally diagonally thereacross. A frame supports the tools such that the face of one tool generally opposes the face of the other tool face. Relative movement of the tools causes the workpiece to rotate and move across the faces where it is deformed by the interaction of the respective raised and recessed portions of each tool. The result is a masonry fastener having at least a portion of its body formed into a substantially helical shape.
