摘要：The invention relates to a self-locking fastening device having a screw or nut forfastening at least one first component to another component, the locking effect beingobtained by means of ribs on surfaces that engage with one another, which ribs arechamfered in such a manner that a smooth roller effect is achieved. The fastening devicehas a disc (1) which is constructed on its surface facing the first component (B) such that,when the fastening device is tightened, said disc is held on the first component such thatit cannot rotate and the surface opposite it has ribs (2) which are chamfered in such amanner that, when the screw or nut is tightened, a smooth roller effect is achieved on thesurface of the screw or nut as a result of relative rotation between the surface of thescrew or nut facing the disc (1) and the opposite surface of the disc.
