Izikrufu zekhonkrithi zisetyenziswa kwiiprojekthi ezahlukeneyo ezibandakanya ukulungisa iipleyiti ze-sill, izixhobo zombane, ezimbini ngezine, kunye nezinye izinto ezininzi zokulungisa i-masonry.
1. I-self-tapping screw luhlobo lwe-screw kunye ne-drill bit, ngokusebenzisa ukwakhiwa kwesixhobo esikhethekileyo samandla, ukugaya, ukucofa, ukulungisa, ukuvala ngokupheleleyo.Izikrufu zokuzicofa zisetyenziswa ikakhulu kuqhagamshelo kunye nokulungiswa kwamacwecwe athile abhityileyo, njengokudityaniswa kwepleyiti yentsimbi enombala kunye nepleyiti yentsimbi yombala, ipleyiti yentsimbi enombala, uqhagamshelo lomqadi eludongeni, umthamo wokungena awukho ngaphezulu kwe-6mm, ubuninzi. ayikho ngaphezu kwe-12mm.
2.Ukucofa ukuxhathisa umhlwa komelele.Izikrufu zokucofa zinoxhathiso olomeleleyo lwe-corrosion, nokuba zivezwe kwindawo emanzi kunye nebandayo ngaphandle, ukuxhathisa kwayo ku-corrosion kubaluleke kakhulu.
3. Izikrufu zokucofa zilula ekusebenzeni okusebenzayo.Isiphumo sempahla ekrwada yokhuni sithambile, ngaphandle kokugrunjwa, sinokujijwa ngaphakathi.
4. Self tapping screw self-drilling isakhono.Ngokuqhelekileyo umgangatho we-screws uxhomekeke kwi-screw diameter, inani leentambo zangaphandle kunye nobude obupheleleyo be-screw rod.Xa sithetha ngokuthelekisa, isikrufu esinenani elingaphezulu leentambo zangaphandle sinamandla okuzibhora.
