摘要

The nut has a circular body (2), whose a ring opening includes an internal thread (3), where the nut is secured against unintentional loosening using a securing device (5). An adjusting unit (10) e.g. setscrew, is assigned to the securing device, where the securing device includes a protection sleeve (11) that partially forms the internal thread and assigned to the ring opening. Threaded edges of the protection sleeve are connected with threaded edges of a shaft in a force-fit and/or form-fit manner by the adjusting unit.
