FIELD: machine building.SUBSTANCE: nut consists of an internal element with a thread and an external element with a surface for a hex wrench with the possibility of joint screwing and unscrewing. The internal element with the thread is made as a spool with beads, the external element with the surface for a hex wrench from frictional material in the form of a ring is pressed-on to the cylindrical part of the internal element with a possibility of mutual offset. One of the beads is set movably in axial direction over thread relatively to the cylindrical part of the coil with possibility of the friction material crimping.EFFECT: provision for the versatility of using a nut at necessary allowable nut screwing forces.2 cl, 1 dwg |
