ABSTRACT:
A wheel nut has a tapered end adapted to seat in the conical depression in a wheel surrounding a stud hole and sides formed with polygonal wrench flats. The flats at the nut end opposite to the taper are depressed or recessed with respect to the remaining flat surface and are connected to the unrecessed sections by a slight shoulder. A stainless steel sheath covers the recessed sections of the flat so that the free edge of the sheath abuts the shoulder. The sheath forms a domed cover surrounding the end of the nut opposite to the conical end to form an enclosure for the end of a wheel stud extending beyond the nut. In an alternative embodiment the sheath edge is bent radially outwardly and then rebent inwardly to form a flange which abuts the wheel surface surrounding a stud depression.
