Self-drilling screws inodiwa mukuvaka simbi yesimbi nekuda kwekugona kwavo kwakasiyana uye akawanda mabhenefiti. Aya ma fasteners akagadzirwa ane chibooreso chidimbu chinobvisa kudiwa kwekutanga-kuchera, nekudaro kudzikisa zvakanyanya nguva yekuisa uye mutengo wevashandi. Kushandiswa kwavo kwekutanga musimbi-ku-metal kusungirirwa kunopa majoini akasimba uye akavimbika, ayo akakosha mukuumbwa kwekuvimbika kwesimbi. Iwo screws anowanzo kugadzirwa kubva kumusoro-giredhi simbi, kuve nechokwadi chakanakisa kusimba uye kuramba kune shear uye kusimba masimba. Pamusoro pezvo, ivo vanowanzo ratidza machira anosimudzira kusaonda, achiita kuti akwanise kushandiswa kwemukati nekunze. Hunhu hwakakosha hunosanganisira kugona kwavo kupinda muzvikamu zvakakora zvesimbi, kuchengetedza zvakabatikana uye zvakachengeteka zvinongedzo, uye kuramba kusunungura pasi pemavibrations. Pakazere, madhiri ekuzviboorera anobatsira mukubudirira uye hupenyu hurefu hwesimbi yekuvaka simbi, ichipa mhinduro inodhura yemapurojekiti ekuvaka emazuva ano.
