In order to achieve low-cost production of the anchor bolt, simple mounting and high tightening torques of the anchor bolt (1) to be anchored, the deformation chamber (4) open towards the front end of the anchor bolt (1) is closed by a plug (5). A striking pin (15) projecting over the front end of the anchor bolt (1) is inserted in the plug (5) and guided so that the striking pin (15) strikes on an exploder cavity (13) arranged between the plug (5) and the explosive charge (8) when the rear end (2) of the anchor bolt (1) is struck.de608620patent1994-4445422
