Patent ID: 6851759

Claim:
A method for manufacturing a wheel spindle to which a rotor may be attached, the method comprising: fabricating a wheel spindle defining an axis of the spindle; forming an annular flange extending perpendicularly to the axis and having a rotor receiving surface thereof adapted for receiving a brake rotor, and forming a rotor retention screw hole in the flange adapted for receiving a self-tapping screw for retaining the brake rotor against the rotor receiving surface of the annular flange; the annular flange including a second surface thereof separated from the rotor receiving surface by a thickness of the flange; the rotor retention screw hole extending through the thickness of the flange and defines a screw hole axis extending parallel to the axis of the spindle; and the rotor retention screw hole including a generally conical shaped web therein having a first surface thereof converging along the axis of the screw hole in a direction away from the rotor receiving surface, a second surface thereof separated from the first surface thereof by a thickness of the conical web, and a through hole therein extending along the screw hole axis from the first to the second surfaces of the conical web and adapted for engaging the self-tapping sheet metal screw.
