Abstract: This invention relates to an eyeglass frame comprising members, particularly hinge members, which are connected by a screw joint which is protected from becoming loose. The screw joint comprises a single metal part, which consists of a screw, which does not tend to become seized and to become clamped in the relatively movable hinge eyes. Because plastic parts are not required in the joint, the screw may remain installed during soldering work. This is accomplished in that the screw has a conical head portion which tapers with an included angle of 20 to 40 degrees, preferably 30.degree., and when the screw has been screwed into the frame the head of the screw extends in a conical opening in a member of the frame and in said opening defines with said frame member a clearance angle of 1 to 3 degrees and a clearance space axially adjoining the head. In such a joint the screw can firmly be tightened so that the high friction will prevent the screw from becoming loose spontaneously.
