The transitional portion has structure thereon, such as a plurality of alternating curved lobes and flutes, for engagement with a corresponding socket. At least a portion of the lobes are threaded in the transitional portion. The drive head also has structure thereon for engagement with the socket, such as a plurality of alternating curved lobes and flutes. The flutes on the transitional portion are axially aligned with the flutes on the drive head and the lobes on the transitional portion are axially aligned with the lobes on the drive head.
