The invention concerns an arrangement for effecting the locking of a nut or screw, and where the locking element constitutes an integrated part. It involves a locking washer (3) which is counter sunk in the nut (1) or screw head (2). The locking washer is designed with wedge shaped locking surfaces (4) and is mounted, locking surface against locking surface (5), in nuts or screw heads. Where the arrangement starts to loosen, the wedge shaped locking surfaces begin to clamp together. A wedging effect arises which hinders the application from loosening.<IMAGE> |
