Zomangira konkriti zimagwiritsidwa ntchito m'mapulojekiti osiyanasiyana kuphatikiza kukonza mbale za sill, zida zamagetsi, ziwiri ndi zinayi, ndi zina zambiri zopangira masonry.
1. Self-tapping screw ndi mtundu wa screw ndi kubowola pang'ono, kupyolera mwapadera zida zopangira mphamvu, kubowola, kugogoda, kukonza, kutseka kwathunthu.Zomangira zokha zomangira zimagwiritsidwa ntchito polumikizira ndi kukonza mbale zina zoonda, monga kugwirizana kwa mbale yachitsulo ndi mtundu wa chitsulo, mbale yachitsulo, kugwirizana kwa khoma, mphamvu yolowera nthawi zambiri siposa 6mm, pazipita. osati kuposa 12 mm.
2.Tapping screw corrosion resistance ndi mphamvu.Zomangira zokhotakhota zimakhala ndi dzimbiri zolimba, ngakhale zitawonekera kunja konyowa komanso kuzizira, kukana kwake kwa dzimbiri ndikofunikanso kwambiri.
3. Zomangira zomangira zimakhala zopepuka pochita ntchito.Zotsatira za matabwa zopangira matabwa ndizofewa, popanda kubowola, zimathanso kugwedezeka.
4. Self pogogoda screw self pobowola luso.Kawirikawiri khalidwe la zomangira pogogoda zimadalira wononga m'mimba mwake, chiwerengero cha ulusi kunja ndi okwana kutalika kwa wononga ndodo.Kunena zoona, wononga yokhala ndi ulusi wambiri wakunja imakhala ndi kuthekera kodzibowolera kolimba.
