FIELD: mechanical engineering.
SUBSTANCE: method comprises setting the screws in the opening of the nut and abutting the screw faces against flats provided on the bolt. The screws are mounted on both sides of the longitudinal symmetry lines of the flats. The device comprises nut, bolt, and two screws crewed into the nut for permitting the screws to abut against the bolt flats. The surface of the bolt is shaped into a hexahedron to provide six flats. The screws have spherical ends. The axes of the screws are inclined one with respect to the other by an angle of 90°. According to the second version, the device comprises nut, bolt, two screws screwed in the nuts for permitting them to abut against the flats on the bolt. The surface of the bolt is shaped into a hexahedron whose ribs are rounded. The nut is provided with three threaded openings. The screws have spherical ends and arranged from both sides of the longitudinal symmetry lines of the flat sides.
EFFECT: enhanced reliability and expanded function capabilities.
