Zusammenfassung:	PROBLEM TO BE SOLVED: To drastically save man-powers by unifying a lubricant film treatment to a wire before cold plastic working and a lubrication treatment applied to the surface of a fastening component after a heat treatment for stabilizing fastening property into one process, and to provide a steel wire which can obtain a fastening component exhibiting a stable black appearance regardless of its production process. SOLUTION: The steel wire for fastening components has a lubricant film containing, as essential components, (a) an alkali metal silicate in which the molar ratio of SiO2to M2O (M represents alkali metal) is 2-5, (b) crystalline graphite having an average diameter of
