A vehicle rim and lug nut assembly wherein a series of circumferentially placed lug nuts are disposed about a vehicle rim, each lug nut encased in an inner cylinder which is itself contained in an outer cylinder mounted to the rim with linear bearing means interposed between the inner and outer cylinders so that the former can rotate and slide within the latter, a spring interdisposed between the inner and outer cylinders to resist, in compression, the inward movement toward the vehicle of the inner cylinder. Each inner cylinder has a threaded receptacle on one end which receives the lug from the vehicle drum or hub and a drive opening on the other end which receives the drive anvil of an impact wrench, usually one-half (+E,fra 1/2+EE ) inch in size. This eliminates the loss of the lug nuts and because of the outward movement of the inner cylinder facilitates disengagement of the impact wrench.
