The invention relates to a screw connection for hinge parts, especially of a spectacle frame, comprising a screw that interconnects the hinge parts which engage inside of one another and which have an upper hinge lobe, a lower hinge lobe, and at least one middle hinge lobe. Said screw has a screw head and a screw shank that extends through a first through-opening in the upper hinge lobe and extends through a second through hole in a middle hinge lobe. A thread permits the screw shank to be screwed into the lower hinge lobe. The inventive screw connection also comprises a sleeve which surrounds the screw shank, has elastic properties, and which interacts with the upper and middle hinge lobes when the screw is in a screwed-in state, whereby the diameter (D2) of the second through-opening is less than or equal to the diameter (D1) of the first through-opening. The screw connection is characterized in that the screw (25) has at least one bearing surface for the sleeve (33) with at least one engaging surface (32) that is aligned in the direction of movement in which the screw (25) is unscrewed. |
