Inzira enye, izwi kandi nk'inzira enye zizunguruka cyangwa Phillips yavugaga, ni igikoresho gikora cyane gikoreshwa mugukuraho imbuto ziziga. Ubusanzwe igaragaramo inzira-enye ifite ubunini bune butandukanye bwa sock kuri buri mpera kugirango ihuze ingano zitandukanye zimbuto zikunze kuboneka kumodoka.
Yashizweho kugirango itange uburyo bwihuse kandi bunoze bwo gukuraho cyangwa gukaza utubuto ku ruziga, imirongo ine yinzira ikoreshwa muburyo bwo guhindura amapine cyangwa indi mirimo yo gufata neza imodoka. Ingano itandukanye ya sock yumutwe kuri wrenches ituma abayikoresha bakora byoroshye nimbuto nini zingana bitabaye ngombwa ko bahinduranya ibikoresho byinshi.
Ubusanzwe iyi wrenche ikozwe mubikoresho biramba, nkibyuma cyangwa chrome vanadium, byemeza imbaraga nigihe kirekire kugirango ukoreshwe kenshi. Nibimwe mubikoresho bigomba-kuba bifite abakunda ibinyabiziga, abakanishi babigize umwuga, nabakeneye gukora ibinyabiziga.
Inzira enye zifite inzira zikurikira:
Muri rusange, inzira-4 yinzira nigikoresho gikomeye, cyoroshye kandi gifatika kumurongo mugari wimbuto zingana, hamwe nigihe kirekire hamwe nurwego runini rwa porogaramu.
