A group of fastening elements such as a nut, a washer, and a lock washer are held together in axial alignment by a sleeve of shrinkable material which embraces the fastening elements and is shrunk by heat or the like to bear against the outer periphery and ends of the grouping of fastening elements. The fastening elements are prearranged in serial order to fit in cooperative relationship with a related fastening element such as a bolt. An opening is left in at least one end of the shrunk plastic sleeve so that the group of fastening elements can be assembled as a unit with the related fastening element while held in prearranged relationship by the sleeve.
