FIELD: machine building.
SUBSTANCE: tightening method of a high-load threaded joint of parts, which consists of attached parts and a load-carrying bolt, consists in the fact that into the load-carrying screw attaching the parts, there screwed is an additional load-carrying bolt, into which an additional securing bolt is screwed, which creates additional compressive stress and distributes a tightening torque proportionally till the acceptable manual tightening force of each of telescopically located bolts.
EFFECT: improving productivity and reducing labour intensity of the connection of the structural elements without using any complex tightening devices.
