Abstract

An earthing nut (1), especially for attaching metallic closures to switching cabinet doors, having teeth (6) which are constructed on both end surfaces (4), are sharp in the fixing rotation direction and are formed in each case by a material displacement with simultaneous formation of a depression (8) which is located in front of the tooth cutting edge (7). In order to improve earthing nuts (1) of the generic type which prevent, in particular, scratching of the door leaf outside the surface which is covered by the nut (1) and the appearance of scratched-off paint flakes protruding from under the outer surface of the earthing nut (1), it is proposed that the teeth (6) be constructed in each case in the region of smallest width between the corners (3) of the nut (1) and with a cutting-edge shape which is constructed at an acute angle with respect to the radial extent of the nut (1), with outer cutting-edge corners (9) which project in the fixing rotation direction. <IMAGE>
