A turbocharger includes a compressor wheel and shaft assembly in which a threaded connection is provided between the shaft and the compressor wheel. A pair of pilot surfaces on the shaft and on the compressor wheel are located on either end of the threaded sections of the shaft and compressor wheel, and are displaced radially from the threads. Accordingly, the piloting functions which assure concentricity between the shaft and compressor wheel are kept entirely separate from the attachment function provided by the threads, thereby permitting the concentricity between the compressor wheel and shaft to be held to tighter tolerances than would be possible if the threads also performed a piloting function.
