Caulking referred to in the art securing a screw joint against undesired loosening by a blow with a targeted grains against the threaded end. As a result, the thread is damaged in a small area so that the screw connection can only be loosened with the application of force against a resistance.

Securing by caulking cannot be repeated at the same point as often as desired, since the material is permanently deformed. Often there is a longitudinal groove on the screw connections to be secured on the external thread, into which a projection (securing collar) provided on the internal thread of the nut is bent ("caulked") by hammering.
