A screw connection for hinge parts, especially of an eyeglass frame, comprising a screw that interconnects the hinge parts that engage one inside the other and that have an upper hinge lobe, a lower hinge lobe, and at least one middle hinge lobe, the screw having 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 opening in the middle hinge lobe, with a thread permitting the screw shank to be screwed into the lower hinge lobe, and comprising a sleeve that surrounds the screw shank, has elastic properties, and interacts with the upper and middle hinge lobes when the screw is in a screwed-in state, whereby the diameter (D 2 ) of the second through opening is less than or equal to the diameter (D 1 ) of the first through opening. The screw connection is distinguished by the fact 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. |
