Abstract:
A lug nut for securing a wheel to a vehicle axle bolt comprising:a lug nut having a proximal end and a distal end, the lug nut defining a threaded hole for receiving a bolt, the threaded hole extending along a longitudinal axis of the nut between the proximal end and the distal end;an outer perimeter of the proximal end defining a tapered, conical surface, the tapered surface diverging outwardly from the proximal end and defining a terminal portion along a midsegment of the lug nut exterior;the midsegment of the nut having a perimeter surface defining a plurality of ridges, each one of the plurality of ridges being connected to an adjacent ridge by an interconnected concave surface, the perimeter surface decreasing in size from a proximal end to a distal end of the lug nut said distal end being flush with respect to said ridges and said interconnecting concave surfaces; and,each ridge opposite one of said concave surfaces, an axial length of each said concave surface being greater than an axial length of each of said ridges.
