Abstract:
1. A fastener arrangement comprising: a component; and a screw element with a force application area for a turning tool, where the component and the screw element—when they have been attached—are in contact with each other by way of contact surfaces, and where the contact surface of the screw element on the side facing the component is configured as a convexly curved outer surface, and the contact surface of the component is configured as a concavely curved inner surface, while the outer surface and the inner surface are positioned coaxially with respect to a common longitudinal axis, which extends through the component and the screw element, the contact surfaces when viewed in the axial cross section of the fastener arrangement define circular sections each having two ends and being curved in such a manner, that centers of curvature of the circular sections of the convexly curved outer surface are spaced from centers of curvature of the circular sections of the concavely curved inner surface in a direction proceeding perpendicularly to the longitudinal axis in such a manner that the contact surfaces are in contact with each other between the ends of their circular sections when they are fastened, wherein the centers of curvature of the circular sections of the concavely curved inner surface define a common center of curvature B, and the centers of curvature of the circular sections of the convexly curved outer surface are, in the direction extending perpendicularly to the longitudinal axis, spaced from each other, where radii belonging to the centers of curvature of the circular sections of the concavely curved inner surface are longer than radii belonging to the centers of curvature of the circular sections of the convexly curved outer surface.
