Abstract: An expansion anchor having an anchor bolt, an expansion sleeve surrounding the anchor bolt, and an expansion body located in a front region of the anchor bolt, wherein the expansion body has a converging zone for expanding the expansion sleeve. The expansion body has at least one expansion sleeve abutment wall facing the expansion sleeve. The invention also relates to a method for using such an expansion anchor.

Abstract: An expansion dowel is provided, which includes at least one dowel body and a bolt, the bolt including an expansion body, which forces the dowel body radially to the outside when the expansion body is displaced in an extraction direction relative to the dowel body, a corrosion protection layer and an antifriction layer covering the corrosion protection layer being provided on the expansion body. It is also provided that the corrosion protection layer is a Zn/Ni coating or a Zn/Fe coating. A manufacturing method for an expansion dowel of this type is also provided.

Abstract: A method for fixing an expansion anchor to a substrate includes introducing an anchoring zone and at least one part of a middle zone of a bolt of the expansion anchor into a hole in the substrate together with an expansion sleeve of the expansion anchor. The bolt is then moved relative to the expansion sleeve in a pull-out direction, as a result of which the expansion anchor is anchored to the wall of the hole. The space between the wall of the hole and the bolt is then filled to the height of at least one part of the middle zone with a curable mass such that the curable mass on the middle zone reaches up to an annular collar of the bolt, where the collar is configured as one piece with the bolt and is locally larger in cross-section, and the curable mass is cured.

Abstract: A setting tool includes an anchor rod holder (31) open toward a front side of the setting tool, and a drill holder (41) that is open toward a rear side of the setting tool. The setting tool includes a passage (3) through which an anchor rod (10) accommodated in the anchor rod holder (31) may be directly, axially acted on percussively by a drill (20) accommodated in the drill holder (41). Moreover, a fastening arrangement that includes such a setting tool is provided.
