A cover for a bolt and nut having a plurality of generally planar, annular surfaces comprises a shell including a closed end portion and a plurality of side surfaces extending downwardly from the closed end portion. Each side surface has a generally planar inner wall that terminates in the bottom wall adapted for adjoining a flat surface of the wheel rim mounted on a vehicle with a plurality of such bolts and nuts. The cover further comprises a clip for inserting into the cavity defined by the shell side surfaces. This clip includes an annular ring and a plurality of spaced projections extending downwardly from the ring's perimeter, each projection adapted for engaging an annular nut surface when the cover is installed thereover. The cover further comprises means for retaining the clip within the shell cavity. Preferred retaining means include: at least one inward protrusion from each inner wall against which a clip projection end section will engage when the clip is inserted into the cavity; and at least one pair of ring locators extending inwardly and axially along opposing inner walls of the shell. On a preferred basis, this outer shell is made from chrome-plated plastic and the clip from a zinc-plated metal such as steel, brass or aluminum.
