FIELD: machine building.
SUBSTANCE: invention relates to assembly of structures operated at cyclic loads, particularly, bolt joints of aircraft structures. To make bolt joint with radial interference bolt is fitted in bore after washer is fitted on bolt body from the side of threaded part. Nut is screwed on and tightened by specified torque. Bolt is compacted on head side to press the parts with the help of nut. This is effected by application of dynamic load and nut tightening by specified torque. Cycles of nut tightening vary in number depending upon structural peculiarities of parts to be jointed.
EFFECT: higher fatigue strength of bolt joints.
