Zusammenfassung:	An expansion dowel assembly includes a sleeve, a tie rod insertable into the sleeve, an expanding body connected to one end of the tie rod and an end support on its other end. A member is connected to the end support for transmitting torque to it and by virtue of the torque applied to the end support the expanding body is drawn into the sleeve causing to expand. Shear pins connect the member to the end support and when a predetermined torque is reached the pins shear off and the member can be removed from the end support. The shear pins can be arranged either parallel or perpendicular to the axis of the tie rod.
