Maboliti owerengera, omwe amadziwikanso kuti zomangira zowerengera kapena zomangira, ndi mtundu wamba wa zomangira. Mwachiwonekere, mutu wa bolt wa countersunk umakhala ndi koni ya 90-degree tapered yokhala ndi zida zomangirira, zopezeka mu masitaelo monga slotted, Phillips, hex socket, nyenyezi, ndi pentagonal.
Zomangira zimagwiritsidwa ntchito kulumikiza zinthu ziwiri, koma mutu wa screw wokhazikika umatuluka pamwamba pa chinthu cholumikizidwa, ndikusokoneza kusalala kwake. Komabe, ma bolt a Countersunk amatha kutsukidwa pansi pamadzi, kukhalabe osalala. Pazinthu zolimba, dzenje loyendetsa liyenera kubowoleredwa pamalo oyikapo musanamize chomangira.

Zochitika za Ntchito

Kupanga Makina

M'zida monga zida zamakina ndi zochepetsera, ma bolts a countersunk amalepheretsa kugundana kwamutu ndi magawo osuntha, kumapangitsa chitetezo.

Makampani Omanga

Amagwiritsidwa ntchito polumikizira zida zachitsulo kapena kuyika khoma lotchinga, kuwonetsetsa kusalala kwa pamwamba pomwe amachepetsa kukana kwa mphepo kapena kuwopsa kwa madzi.

Zida Zamagetsi

Mu zida zolondola kapena misonkhano yanyumba, mabawuti osunthika amalepheretsa kukwapula kwa mutu kwa ogwira ntchito ndikupewa kusokoneza masanjidwe adera.
