Abstract: The invention relates to an anchor (1) that can be secured in a drilled hole (2), with an expansion sleeve (10) for anchoring onto a wall (3) of the drilled hole, and with an anchor bolt (20) that passes through the expansion sleeve and that has an expansion section (38) for widening the expansion sleeve, and it also has a stop (22) that limits axial movement of the expansion sleeve away from the expansion section. According to the invention, at least one rotary catch (24) is provided which non-rotatably couples the expansion sleeve to the anchor bolt, and the expansion sleeve has at least one cutting projection (14) for creating an undercut in the wall of the drilled hole.
