Securing screw with screw head, and process for radially securing the screw connection

摘要

The shank part (3) of the securing screw is configured in a thickened manner. On tightening the screw, material of the connecting part (5) directed towards the screw head is pressed, by means of the thickened shank part, into a cutout (7) in the connecting part (5') located therebeneath. The screw consequently achieves a secure fit in the connecting parts (5 and 5'). Spontaneous loosening of the screw in the screw connection is thus counteracted. <IMAGE>
