The washer has a central hole (21) for introducing the screw shank. A tubular extension (20) aligned axially parallel to the screw shank (9) to be inserted adjoins the central hole (21) in the washer (6). Sections or parts of this extension (20) engage by plastic deformation in the threaded region (8) of the screw shank (9) to achieve preassembled retention of the washer (6) and screw (5).
