    • A combination of a dual wheel for a vehicle and clamping nuts for securing this wheel to studs on a wheel hub including inner and outer wheel assemblies having respectively inner and outer metal wheels. Each wheel includes a wheel disk having a number of stud-receiving holes of predetermined length. Each nut has a central, threaded passageway, wrenching surfaces formed on a head portion, and an integral, cylindrical skirt portion which has an outer diameter slightly less than the diameter of the holes in the outer metal wheel. A washer is rotatably mounted on each nut and has an outer side engaging an inner end of the head portion. During use of the nuts and the washers, a section of each skirt portion projects only into a respective one of the holes formed in the wheel disc of the outer wheel. The length of this section is equal to or less than the length of the holes in the outer wheel.
