Abstract
A composite fastener which is comprised of a nut having a neck at one of its axial ends, and of a washer which at least partially surrounds the neck and is adjacent an external shoulder of a non-circular main section of the nut. That end of the neck which is remote from the shoulder is expanded to prevent an unintentional separation of the washer from the nut. The making of an internal thread in the nut is carried out subsequent to the expansion of the neck. The nut and the washer can constitute converted blanks which are converted by resorting to a press forging or cold forming or turning procedure.
