Abstract
A plate provides guides for preferably two screws, which hold the screws in a stable way at an angle against the plate. Furthermore, the screws are preferably fixed in a stable and removable way with a clamping device against rotations around the screw barrel and shifts in the direction of the screw barrel. For this a special screw is suitable with an outer thread diameter, which is larger than the neighboring barrel diameter. To ensure a secure guidance, the barrel diameter is enlarged in the area of the screw head.
