A lug nut and dress cap that enables a standard sized lug wrench to be employed whether the cap is in place or lost, the cap having the same standard lug wrench size as the nut. The cap is a deep drawn element having a hollow hexagonal configuration adjacent its outer closed end and specially formed threads adjacent its inner open end that interlock with the cut machined threads of the lug nut. The cap threads have a curvilinear, radiused root and a curvilinear, radiused crest. The cap outer end extends beyond the lug nut. The middle or intermediate portion of the cap between the hexagonal outer end portion and the threaded inner end portion has a diameter larger than the diameter of the hexagonal portion of the cap and larger than the diameter of the hexagonal outer end of the lug nut.
