Mfundo yogwirira ntchito ya wrench ya gear yosasunthika imakhazikitsidwa makamaka pamakina a ratchet. Wrench ya ratchet ili ndi njira yolumikizira mkati yomwe imakhala ndi magiya angapo ndi gudumu la ratchet. Chogwiriracho chikayambika, magiya amazungulira zida zothamangitsira, zomwe zimapangitsa kuti pakhale mphamvu imodzi yozungulira pa wrench. Kapangidwe kameneka kamathandiza kuti wrench izungulire mbali imodzi yokha, kutsata koloko kapena kopingana ndi koloko, kulimbitsa kapena kumasula mabawuti ndi mtedza.
Wrench ya giya yosasunthika ili ndi izi: choyamba, kapangidwe kake ka giya kamakhala kolondola komanso kolimba, kokhala ndi mphamvu yothina mwamphamvu, yosavuta kutsetsereka, komanso yosavuta kugwiritsa ntchito. Kachiwiri, chogwirira cha wrench chimagwiritsa ntchito kapangidwe ka rubberized ndipo chimakhala ndi anti-slip pattern, yomwe imakhala yosavala komanso yotsutsa, komanso yomasuka kugwira. Kuphatikiza apo, ma wrenches osasunthika nthawi zambiri amapangidwa ndi zinthu zolimba kwambiri, monga chitsulo cha carbon, kuti zitsimikizire kulimba kwawo komanso kutulutsa kwa torque yayikulu. Zinthu izi zimapangitsa ma wrenches osasunthika kukhala okhazikika komanso ogwira ntchito.

Tsatanetsatane wa malangizo kapena masitepe ogwiritsira ntchito bwino wrench yamagetsi osasunthika ndi awa:
Potsatira njira zomwe zili pamwambazi, mutha kuwonetsetsa kugwiritsa ntchito moyenera wrench yamagetsi osasunthika ndikuwonetsetsa kuti ntchitoyo ndi yotetezeka komanso yogwira ntchito.
