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.
