Choyamba, athuzomangira zopanda madzizidapangidwa ndi hexagon countersunks, zomwe sizimangopangazomangirazosavuta kukhazikitsa, komanso ali ndi mwayi odana kupotoza kupereka amphamvu kugwirizana. Zokhala ndi luso lapamwambamakina osindikizira screwgaskets kuonetsetsa chisindikizo changwiro pa unsembe, kuteteza chinyezi, fumbi ndi zinthu zina zoipazomangira zosindikizira za countersunkkulowa mgulu. Mbali imeneyi imalola zomangira zosindikizira osati kungopereka mgwirizano wamphamvu, komanso kuti mgwirizano ukhale wouma komanso woyera nthawi zonse.
Kachiwiri, m'malo akunja kapena kukhudzana ndi chinyezi kwanthawi yayitali, ochiritsirawononga madzi osindikiziraamatha dzimbiri komanso kumasuka. Zathuzomangira zitsulo zosapanga dzimbiriamalimbana ndi dzimbiri komanso nyengo, motero amalumikizana motetezeka ngakhale panja panja. Kaya ndi mipando yakunja, nyumba zomangira kapena zida zamafakitale, sealing screw countersunkkuonetsetsa kuti nthawi yayitali ikugwira ntchito mwamphamvu komanso yodalirika.
Pomaliza, wathuhexagon yopanda madzi screwimaperekanso chokongoletsera chabwino kwambiri, ndipo mapangidwe a hexagon amapangitsa kuti ikhale yosalala ndi pamwamba pambuyo pa kukhazikitsa ndipo sichiwonongeka mosavuta. Nthawi yomweyo, timapereka mitundu yosiyanasiyana yamitundu ndi mitundu kuti tikwaniritse masitayelo ndi zosowa zosiyanasiyana.
