Spherical washers and conical seats are used for transmission of tension forces to adjust tension elements, if the tension surfaces are not parallel to each other. The combination of spherical washers and conical seats allows a deviation of the tension bolt by 3°. For slots use only conical seats form G. Form D use only for closed and plain surfaces, not for slots.
