FIELD: machine building.
SUBSTANCE: method and device for tightening and loosening of a high-load threaded joint consisting of two parts being coupled, a threaded rod with a flange head and a set of washers made from shape memory material which are divided by thermoinsulating spacers between each other and between other pairs, one of the washers is predeformed in axial direction and at individual heating provides for tightening force and the second washer is predeformed in its section in the radial direction and (if disassembly is required) at individual heating loosens the tightening.
EFFECT: improved productivity and reduced labour intensity of assembly-disassembly operations at making high-load threaded joints.
