1. I-screw edibeneyo ligama eliqhelekileyo elisetyenziswayo ekwakhiweni kweeprojekthi zokwakha, ebonisa ukuba ububanzi bentsimbi yentsimbi bungaphantsi kweemilimitha ezilishumi;
2. Ngenxa yokuba iintsimbi zetsimbi ezingaphantsi kweemilimitha ezilishumi zilula ukugoba, ukwenzela ukunciphisa ubude ngaphambi kokuthutha, umenzi ujikeleza imivalo yensimbi ende kwisangqa, kwaye iintsimbi zetsimbi zibhekiswa njengezangqa ezidibeneyo kwiindawo zokwakha;
3. Isetyenziswa ngokubanzi kulwakhiwo lobunjineli boluntu njengezindlu, iibhulorho, iindlela, njl.
4.Ikhoyili yesikrufu sentsimbi yokwakha
Intsimbi yokwakha, njengoko negama libonisa, yirebar edityaniswe ndawonye njengocingo. Ngokuqhelekileyo, ininzi yentsimbi kwimarike yi-6.5-8.0-10-12-14. Ngokuqhelekileyo, ngexesha lokunikezelwa, i-snails edibeneyo ilinganiswe, ngokukodwa ngenxa yokuba i-coiled coil ihlanganiswe kwaye ayikwazi ukujongwa. Ngelo xesha, kwimarike yensimbi yanamhlanje, kukho amabakala amathathu kuphela eenkumba ezidibeneyo.
