wherein the nut (40) has a nut hole (41) and an internal thread (64) projecting into the nut hole (41);
wherein the anchor bolt (30) has an anchor portion (31) and a threaded rod (37) that has an external thread (63) and that is connected to the anchor portion (31) to transfer a tensile force into the anchor portion (31);
wherein the nut (40) is arranged on the threaded rod (37) and the internal thread (64) of the nut (40) threadedly engages the external thread (63) of the threaded rod (37);
wherein the nut (40) comprises a rearward nut section (43), a forward nut section (45) which is located closer to the anchor portion (31) of the anchor bolt (30) than the rearward nut section (43), and an outside shoulder (44) for load transfer into the nut (40) which is located between the forward nut section (45) and the rearward nut section (43) and which faces the anchor portion (31) of the anchor bolt (30);
wherein the internal thread (64) of the nut (40) extends at least in the forward nut section (45) and the internal thread (64) of the nut (40) threadedly engages the external thread (63) of the threaded rod (37) at least in the forward nut section (45);
