Abstract: The invention relates to an expansion anchor (10) comprising an expansion sleeve (12) which is divided into expansions (18) by means of longitudinal slots (14) arranged in the front section in the direction of placement (16) of the expansion sleeve (12) and also has an inner thread (20) in the rear section in the direction of placement (16). The expansion anchor (10) further comprises an expansion body (22), which preferably has the shape of a cone stump that tapers conically in the direction of placement (18), the conical stump being arranged in the front section in the direction of placement (16) of the expansion sleeve and inside the expansion sleeve (12).

Abstract: The invention relates to a system comprising a composite anchor bolt (10) and glue (12), wherein the bolt (10) can be screwed directly into a bore (14) that is at least partially provided with the glue (12) and is introduced in a fixed anchoring base (16), wherein the bolt (10) has a bolt head (18) having a tool application element, a substantially cylindrical shaft (20), and two or more, however, preferably three thread turns (22, 24, 26), which are disposed parallel to each other and extend helically at least partially across the length of the shaft (20), wherein the respective distance (p1, p2, p3) between the thread turns (22, 24, 26) is selected such that the glue (12) present in the bore (14) is evenly distributed between the wall (32) of the bore (14) and the bolt (10) upon screwing the bolt (10) into the bore (14).
