Abstract

A setting method of anchoring a fastening element (11; 41) in a constructional component (21) with a hardenable multi-component mass (31) includes drilling a borehole (22) in the constructional component (21) with a drill (36) until a borehole depth (T), which is at least by 5% greater than a necessary anchoring length (L) of the fastening element (21; 41), is reached; introducing the hardenable multicomponent mass (31) in the uncleaned borehole (22), inserting, in the borehole (22) the fastening element (11; 41) with its mixing section (13; 43) first, and power-driving the fastening element (11; 41) into the filled borehole (22) with a rotary driving tool, with intermixing of the hardenable multi-component mass (31) with drillings (23) remaining in the borehole (22), until the necessary anchoring length (L) of the fastening element (11; 41) is reached.
