FIELD: machine building.
SUBSTANCE: between a nut and connected details a belleville spring made from alloy based on titanium nickelide is placed, which is pre-cooled down to the temperature -80°C - -120°C. The nut is tightened until the strain of the cooled belleville spring into a flat washer. At temperature increase up to the ambient temperature, the flat washer tends to restore its initial state and provides guaranteed torque of the threaded connection.
EFFECT: decrease of torque with simultaneous provision of necessary and sufficient torque of the threaded connection due to the shape memory effect of the alloy based on titanium nickelide.
