摘要

The device (1) has inner-side surfaces (3) at a recess (5) of the device. A support surface (7) is provided perpendicular to areas of the inner-side surfaces of the device. The areas of the inner-side surfaces are placed at lateral plane outer surfaces in the recess. The device is magnetically formed in a region of parts of the support surface. A cover (9), a projection or a bar over a part of the recess is provided on a side opposite to the support surface for partially covering a screw head or a screw nut passed into the recess of the device.
