Zomangira za matabwa, monga momwe dzinalo likusonyezera, zimapangidwa kuti zigwiritsidwe ntchito ndi matabwa, ndipo mitundu yosiyanasiyana imapezeka monga mutu wozungulira, mutu wathyathyathya, ndi mutu woviikidwa m'madzi.
Pa ntchito zolemera zokhudzana ndi konkriti kapena miyala yamwala, zomangira za konkriti ndizo zomwe anthu ambiri amakonda. Zomangirazi zimakhala ndi ulusi wodzigwira okha ndipo zimafuna mabowo obooledwa kale. Zomangira za hex, zomwe zimadziwika ndi mutu wawo wa hexagonal, zimapereka mphamvu yogwira bwino ndipo zimagwiritsidwa ntchito kwambiri m'mafakitale a magalimoto ndi makina. Mofananamo, zomangira za denga zimapangidwa kuti zigwirizane ndi zinthu za denga, ndipo zomatira zake sizimagwa mvula komanso zimateteza ku kuzizira.
Ponena za mitu ya screw, pali mitundu ingapo yoti musankhe. Zomangira za Countersunk (CSK) zimakhala ndi mutu womwe umakhala wofewa kuti ukhale wosalala pamwamba, zomwe zimapangitsa kuti ziwoneke bwino komanso zosalala. Zomangira za mutu wa hex, zokhala ndi mawonekedwe ake a mbali zisanu ndi chimodzi, zimapereka mphamvu yowongolera mphamvu, zomwe zimapangitsa kuti zikhale zoyenera kugwiritsidwa ntchito ndi torque yayitali. Zomangira za mutu wa pan zimakhala ndi pamwamba pozungulira pang'ono ndipo zimagwiritsidwa ntchito kwambiri pamagetsi ndi mipando. Zomangira za pan truss zimakhala ndi mutu waukulu, wosalala, womwe umapereka malo ochulukirapo komanso mphamvu yowonjezera yogwirira. Zomangira za pan washer zimaphatikiza mawonekedwe a mutu wa pan ndi washer kuti zigawire katundu ndikuletsa kuwonongeka kwa pamwamba. Zomangira za hex washer, kuphatikiza ubwino wa mutu wa hex ndi washer, zimapereka mphamvu yowonjezera yogwirira.
Kusankha dalaivala, chida chomwe chimagwiritsidwa ntchito poika ndi kuchotsa zomangira, n'kofunika kwambiri. Madalaivala a Phillips, omwe adapangidwira makamaka zomangira za mutu wa Phillips, amagwiritsidwa ntchito kwambiri chifukwa cha kusinthasintha kwawo. Madalaivala okhala ndi mipata, okhala ndi tsamba lathyathyathya, amagwiritsidwa ntchito pa zomangira zachikhalidwe zokhala ndi mipata. Madalaivala a Pozidriv, okhala ndi mawonekedwe a nyenyezi, amachepetsa kutuluka kwa cam ndikupereka mphamvu yowonjezera. Madalaivala a square hexagon, omwe nthawi zambiri amatchedwa square drive, amapereka mphamvu yogwira bwino komanso kutsika pang'ono.
Pamene njira zathu zoyendetsera zomangira zasintha, mitundu yosiyanasiyana ya zomangira, mitundu ya mitu, ndi zosankha za oyendetsa zakula, zomwe zimagwirizana ndi mitundu yosiyanasiyana ya ntchito ndi zipangizo. Kaya ndi kusonkhanitsa mipando, kumanga nyumba, kapena kuchita mapulojekiti a DIY, kusankha zomangira zoyenera, mtundu wa mutu, ndi choyendetsa ndikofunikira kwambiri kuti tikwaniritse zotsatira zotetezeka komanso zolimba. Zatsopano muukadaulo wa zomangira zikupitilira kupita patsogolo, nthawi zonse zimawonjezera magwiridwe antchito komanso kusavuta komwe timachita poyendetsa zomangira.
