SELF-CUTTING UNDERCUT ANCHOR

The invention proposes forming expansion elements (13) of an expansion sleeve (9) of a self-cutting undercut anchor (1) comprising forwardly projecting bracket elements (20) which can be pivoted outwards by bending such that they adapt to an "incline" of a frustoconical expansion body (7)...

description	The invention proposes forming expansion elements (13) of an expansion sleeve (9) of a self-cutting undercut anchor (1) comprising forwardly projecting bracket elements (20) which can be pivoted outwards by bending such that they adapt to an "incline" of a frustoconical expansion body (7) of the undercut anchor (1) such that they rest flat against the expansion body (7), instead of resting thereagainst with a circumferential edge. The bracket elements (20) have a lever arm in relation to cutting edges (18) of the expansion elements (13), which lever arm increases an expansion force.
