  • Patent number: 5501559
    Abstract: A screw connection includes a first component having an outer surface and a countersunk bore extending from the surface and having a cylindrical portion adjoining the outer surface of the first component. There is further provided a second component adjoining the first component. A screw passes through the countersunk bore and extends into the second component for joining together the first and second components. The screw includes a screw head having an end face which is recessed relative to the outer surface. A disk is press-fitted into the cylindrical portion of the countersunk bore. The disk has a surface oriented toward the end face of the screw head. The disk surface has a center part which is in direct or indirect contact with the end face of the screw head. A circumferential marginal part of the disk is at a clearance from the end face of the screw head whereby an externally applied pressing force on the disk at a disk location spaced from the center part causes a rocking motion of the disk.
