   In Fig. 7, a screw nut equipped with the lock can be seen in plan view.



     FIGS. 8-10 show a particularly advantageous embodiment of the penetrating end 7a of the locking pin 7. This pin end then runs out in a wedge shape into a straight cutting edge 12. Fig. 8 shows the narrow and Fig. 9 the broad side of the wedge.

 located in the fact that no rotational movement of the locking pin can take place.



   PATENT CLAIMS:
1. Screw locking, consisting of a locking pin which axially penetrates the head of a screw or a screw bolt or a nut and penetrates with its sharpened end into the workpiece forming the contact surface, characterized in that the locking pin penetrating the bore is smooth (threadless ) is and in the screw head (1) or in the screw nut a only over the middle part of the height of the or. the same extending recess (4) is provided, which extends at least up to the plane of symmetry of the bore (2), such that the bore is open in the middle part towards the recess as a channel.
