A fastener for use with inch and metric wrenches has a body unitarily formed with at least one screwthread, a pair of concentric faceted tool-fitting regions of different sizes, and a step between the regions. One of the regions corresponds to a metric wrench size and the other of the regions corresponds to an inch wrench size. The screwthread and both regions are coaxial.
