Abstract
A device for torque limiting, has a nut having a female thread. A holding element includes 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 a receiving part having a receptacle in a front area of the holding element, in which the nut is rotatably fixedly accommodated, the top part having a passage, through which a threaded rod screwed into the nut may be led out of the holding element through the top part along the longitudinal axis of the device. The holding element includes a web connecting the receiving part and the top part and which forms a predetermined breaking point. In at least one longitudinal sectional plane of the device, the smallest wall thickness of the at least one web is present on a line segment of minimum wall thickness, which runs at an angle greater than 45° with respect to the longitudinal axis of the device. A fastening arrangement includes the device.
