Abstract: In a device for producing self-locking properties of a screw and nut device the nut co-operates with a torque-transmitting part which is rotatable in relation to the nut. Torque is transmitted via a portion on the torque-transmitting part, which portion is arranged in a space between two opposing surfaces on the nut. A helical spring is arranged in a thread around a threaded shaft and has an end portion inserted into the space. The helical portion of the spring has a loose fit in the thread when the nut is driven by the part, whereas the spring is contracted against the shaft when the end portion contacts one of the opposing surfaces of the nut and thereby brakes the rotation if the nut tends to be rotated by an axial load on the nut and the part is disconnected.
