Izikulufu zikakhonkolo zisetshenziswa kumaphrojekthi ahlukahlukene okuhlanganisa ukulungisa amapuleti e-sill, izinto zikagesi, ezimbili ngamane, nezinye izinto eziningi zokulungisa amatshe.
1. I-self-tapping screw iwuhlobo lwesikulufu esine-drill bit, ngokusebenzisa ukwakhiwa kwethuluzi elikhethekile lamandla, ukubhoboza, ukuthepha, ukulungisa, ukukhiya okuphelele.Izikulufu ezizithephayo zisetshenziswa kakhulu ekuxhumeni nasekulungiseni amapuleti athile azacile, njengokuxhunywa kwepuleti lensimbi lombala kanye nepuleti lensimbi lombala, ipuleti lensimbi lombala, uxhumo lwensimbi yodonga, umthamo wokungena ngokuvamile awubi ngaphezu kuka-6mm, umkhawulo hhayi ngaphezu kuka-12 mm.
2.Ukumelana nokugqwala kwesikulufa kunamandla.Izikulufu zokuthepha zinokumelana nokugqwala okuqinile, ngisho noma zivezwe ngaphandle okumanzi nokubanda, ukumelana nokugqwala kwazo kubaluleke kakhulu.
3. Izikulufu zokucofa zilula ekusebenzeni okungokoqobo.Umthelela wempahla eluhlaza yokhuni uthambile uma kuqhathaniswa, ngaphandle kokubhoboza, ungaphinda ufakwe ngesikulufu.
4. Ikhono lokuzibhoboza ngesikulufu ngokwakho.Ngokuvamile ikhwalithi yezikulufi zokucofa incike kububanzi besikulufu, inani lemicu yangaphandle kanye nobude obuphelele benduku yesikulufu.Uma kuqhathaniswa, isikulufu esinenombolo eyengeziwe yemicu yangaphandle sinekhono eliqinile lokuzibhoboza.
