Abstract
A self-attaching fastener includes a pilot portion having an outer side wall and is surrounded by an annular flange. The annular flange includes a planar end face defining a peripheral edge with a diameter greater than a diameter of said outer side wall of the pilot portion. The end face includes a plurality of first circumferentially spaced anti-rotation elements each having a planar top face spaced above the planar end face of the annular flange and a second plurality of second circumferentially spaced anti-rotation elements each having a planar top face spaced below the planar end face of the annular flange. Each of the first and second anti-rotation elements extend from about one of the peripheral edge of the annular flange and the outer side wall to a location spaced from the other of the peripheral edge of the flange portion and the outer side wall of the pilot portion.
