FIELD: machine-building.
SUBSTANCE: invention related to machine-building and can be used for tightened unit manufacture. Install loaded unit in to connection part hole. Move forward one or more operation tools for deformation relatively to connecting part in a way, that to deform at least one of the hole walls during clutching with the loaded unit. At least one loaded unit and first connection part tightened together in a way that at least one loaded element dislocated relatively to cross-section center of first connection part. Loaded element installed into hole, limited with wall, and connection part deformed along its perimetre for mentioned before wall clutching interaction with loaded element, with deformation ratio at its certain length, changing dependently on moving along loaded element perimetre. Lightning protection discharge includes tightened unit. Device for its manufacturing includes connection part holder and at least one deformational tool, which can be shifted to the connection part side, fixed in the holder, and has one or more holes, formed by wall. Loaded element installed into every hole. At that one or every deformational tool executed with possibility of connection part deformation along its perimetre and every mentioned wall during clutching interaction with the loaded element, with deformation ratio at defined length, changing dependently on moving along loaded element perimetre or the nearest element to the loaded element.
EFFECT: unit reliability and tightening efficiency increase.
