METHOD OF MAKING A SWIVEL HOOK ABSTRACT OF THE DISCLOSURE A method for making a swivel hook which has a hook member with a frustoconical projection terminating in a cylindrical extension of diameter less than the smaller diameter end of the frustoconical portion. The mounting member for the swivel hook has a frusto- conical hole into which the frustoconical projection is fitted. The elements of the swivel hook are cast of a metal, or molded of a plastic, in such a manner that the bearing surfaces of one of the elements forms a part of the die for the bearing surface of the other element. During the casting or molding process, the cylindrical extension is beyond the frustoconical hole, and the elements are moved relative to each other following casting or molding to move the cylindrical extension into alignment with the frustoconical hole.
