  • Self-locking threaded element
    Patent number: 6851905
    Abstract: A self-locking threaded element that is used, for example, in a tool receptacle of a grinding tool. The self-locking threaded element comprises a retaining member (1) and a main part (3) axially disposed relative to the retaining member (1) at a distance (a) and connected with the retaining member (1) by a connection web (2). The main part (3) and the retaining member (1) are interspersed with a thread (4) for engaging a counter-thread. The retaining member (1) is displaceable relative to the main part (3), at least in the longitudinal direction (L) of the thread (4), to provide a self-locking threaded element that is inexpensive to manufacture and enables both simple tightening and loosening of the threaded element.
