Abstract
Methods of forming and feeding self-attaching fasteners are disclosed wherein the strip includes a plurality of spaced abutment surfaces, preferably notches, which may be used both during the manufacturing process and feeding of a strip of fasteners to an installation head. Where the fasteners are interconnected in a strip, by frangible wires, the wires are located in the bottom wall of the panel receiving grooves in the flange portions on opposed sides of the projecting pilot portion. A self-attaching fastener having deformable inclined lip portions which extend upwardly and toward the pilot portion from the flange portions which are deformed during installation to provide further securement for the panel when deformed in the grooves.
