N., Student, e-mail: s.tverd@ictemir.kz Novosibirsk State Technical University, 20, Prospect K. Marksa, Novosibirsk, 630073, Russian Federation Abstract The paper presents new possibilities for use in design calculations of screw devices. Proposed settlements due to the introduction in formula the argument "performance" and apply them to computing internal screw geometry. These formulas have the properties of "mutually inverse correspondence" options that allow you to explore the calculations associated with the variation of the parameter values screws. The application of these formulas ensures the objectivity of the calculations, aimed at verification of passport characteristics of screws, the determination their ability to various transportation cargo, the calculation of the product mass on coils of a screw metering device, the increasing performance on surplus power auger motor current. Keywords geometry of screw, mutually opposite compliance, performance, linear load, force, power
