Self-drilling fastener

A self-drilling fastener (11) for chemical anchorage in a base (6) has a hollow-cylindrical receiving body (12) at one end (13) has a drill head (16) and which provides for an extrudable, curable multi-component mass (26) is. The hardenable mass (26) comprises a hardener (27), and a reactive resin (28), which are stored separately and harden in the mixed state. In the drill head (16) through openings (17, 19) for the hardenable mass (26) are provided. The reactive resin (28) includes two different formulations (29, 30) which are arranged one behind the other, wherein the second formulation (30) of the reactive resin (28), which cures rapidly in the mixed state with the hardener (27) in relation to the is arranged the setting direction (S) the fastening element (11) behind the first formulation (29) of the reactive resin (28), which hardens more slowly in the mixed state with the hardener (27).
