A corrosion-resistant, headed fastener, such as a nail for exterior applications, is made from a carbon steel wire pre-coated with a protective, metallic layer having corrosion-resistant properties, the protective, metallic layer being discontinuous at a region on a leading end of the pre-coated wire. After at least part of a protective, metallic cap having corrosion- resistant properties is disposed near the leading end of the pre-coated wire, at least part of the protective, metallic cap is welded to the leading end of the pre-coated wire so as to cover the region where the protective, metallic layer is discontinuous, by impact welding, as a fastener is formed from the pre- coated wire in such manner that the fastener is formed with a shank and with a head, which is formed by deformation of the leading end. The welded part of the protective, metallic cap provides the fastener with corrosion resistance at the region where the protective, metallic layer is discontinuous, and the protective, metallic layer provides the fastener with corrosion resistance elsewhere. The protective, metallic layer is made from chromium, nickel, zinc, aluminum, or an alloy comprising zinc and aluminum, preferably from zinc or such an alloy. The protective, metallic cap is made from chromium, nickel, zinc, aluminum, or an alloy comprising zinc and aluminum, preferably aluminum, which can be visually differentiated from zinc or such an alloy.
