Screweve zikoresha amashanyarazi zikoreshwa cyane mu nganda no mu ngo, akenshi mu gushyiraho cyangwa gukuraho ibifunga bifite imigozi.
Screvedero y'amashanyarazi y'umwuga, ingufu nyinshi ni nini, ibi ni ukugira ngo abanyamwuga bagabanye umutwaro w'akazi, bongere imikorere myiza; Kandi nk'uko bikorwa mu rugo, kuko umushinga ari muto, bityo ingufu z'ubu bwoko bwa screvedero y'amashanyarazi muri rusange ntizikenera byinshi.
Ibisabwa kuri screwdriver nziza ikoresha amashanyarazi kuri moteri ni torque iringaniye n'umuvuduko, ihamye kandi yizewe. Torque nke n'umuvuduko bigira ingaruka ku mikorere myiza, guhitamo moteri ifite ingufu nyinshi bizatuma fuselage ibyimba, iremereye, kandi idakora neza kuyikoresha. Byongeye kandi, ikintu cy'ingenzi kuri screwdriver ikoresha amashanyarazi ni uguhuza ibintu, bisaba ko boxbox ya moteri iguma neza cyane. Muri rusange, ibikoresho by'icyuma bifite ubuziranenge bwo hejuru biratoranywa. Ni byiza kuzuza ibisabwa by'ingenzi byavuzwe haruguru mbere yo gusuzuma neza urusaku n'ubuzima. Kuri screwdriver zikoresha amashanyarazi mu rugo zidakunze gukoreshwa, muri rusange abakora bazahitamo kuzigama ikiguzi kuri ibi bintu bibiri.
