A mechanism for adjusting a member in three degrees with respect to a reference plane comprising three screws with spherical underheads extending through the member and threadably received in a base plate, springs about the shanks of the screws bias the member upwardly while the spherical underheads make at least full fine circular contact in recesses from the upper surface of the member.
The present invention concerns a fastener arrangement made of a component and a screw element with an area for the application of force for a turning tool, where the component and the screw element, when fastened to each other, 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, has a convexly curved outer surface, and where the contact surface of the component has a concavely curved inner surface, while the outer surface and the inner surface are positioned coaxially with respect to a common longitudinal axis, which runs through the component and the screw element.
