FIELD: technological processes.
SUBSTANCE: method of fixation of screws or bolts that are installed in a row in a circle on shaft or casing includes screwdriving of screws or bolts in threaded openings. Screws or bolts are screwed in casing or shaft in line in a circle, while the joined parts are being pressed to each other. Then section of heat shrinkable plastic pipe is installed with clearance above screw or bolt heads, fully covering them, and then this section is further heated along the whole circuit with hot air until it tightly shrinks and embraces casing or shaft together with screw or bolt heads.
EFFECT: fast fixation of screwed fastening element and its reliable protection against dust ingress and corrosion.
