A device for torque limiting, which includes a nut and a holding element including a top part having an entrainment profile in a rear area for the rotatably fixed coupling of the top part with a setting tool. A receiving part has a receptacle in a front area of the holding element, in which the nut is rotatably fixedly accommodated. A device for torque transmission from the top part to the receiving part connects the top part and the receiving part and breaks at a limiting torque, interrupting the connection between the top part and the receiving part. The holding element includes at least one holding claw situated on the receiving part and securing the nut in the receptacle on the front side of the nut. A fastening arrangement made up of an expansion anchor and a device of this type for torque limiting as well as a method for manufacturing a device of this type.
