FIELD: machine building.
SUBSTANCE: invention relates to screw elements for multiple-shaft screw machines with screw shafts rotating pairwise in one direction and cleaning each other pairwise by scraping, to the usage of such screw elements and to the method of the screw elements manufacturing. Technical result is reached by the screw elements for the multiple-shaft screw machines with the screw shafts rotating pairwise in one direction and cleaning each other pairwise by scraping. The screw elements have two or more screw twists Z with an interaxle distance A and an external diameter DE. The sum of angles of ridges at a pair of elements is more than 0 and less than 
and the screw profiles have gaps within 0.001-0.1 in relation to the external diameter DE.
EFFECT: reduced power supply and optimised processing of products in the multiple-shaft screw machine.
