Abstract:
A device for torque limiting is provided, including a holding element for a nut or a screw head, the holding element including a top part having an entrainment profile in a rear area of the holding element for the rotatably fixed coupling of the top part with a setting tool, and the holding element including a receiving part having a receptacle in a front area of the holding element for rotatably fixedly accommodating the nut or the screw head. According to the invention, the holding element includes three torque-transmitting webs, which connect the receiving part and the top part and which form a predetermined breaking point. The invention also relates to a fastening arrangement made up of a device of this type and an expansion anchor.
