Zopangira Zamatabwa
Wood screw, yomwe imadziwikanso kuti screw screw, ndi yofanana ndi wononga makina, koma ulusi wowotcha ndi ulusi wapadera wa matabwa, womwe ukhoza kukulungidwa mwachindunji mu chigawo chamatabwa (kapena gawo) kuti ugwirizane ndi chitsulo (kapena chosakhala chitsulo) yokhala ndi dzenje lokhala ndi chigawo chamatabwa.Kulumikizana kotereku kumasokonekera.
Ubwino wa matabwa wononga ndi kuti ali ndi mphamvu kuphatikiza mphamvu kuposa misomali, ndipo akhoza kuchotsedwa ndi m'malo, amene sawononga matabwa pamwamba ndi yabwino ntchito.
Mitundu yodziwika bwino ya zomangira zamatabwa ndi chitsulo ndi mkuwa.Malinga ndi mutu wa msomali, amatha kugawidwa mumtundu wamutu wozungulira, mtundu wamutu wathyathyathya ndi mutu wa oval.Mutu wa misomali ukhoza kugawidwa mu screw slotted screw ndi cross slotted screw.Nthawi zambiri, wononga mutu wozungulira amapangidwa ndi chitsulo chofatsa ndipo ndi buluu.Chophimba chamutu chathyathyathya chimapukutidwa.Chophimba chamutu cha oval nthawi zambiri chimakutidwa ndi cadmium ndi chromium.Nthawi zambiri amagwiritsidwa ntchito kukhazikitsa tsamba lotayirira, mbedza ndi zida zina za Hardware.Zolembazo zimatsimikiziridwa ndi m'mimba mwake ndi kutalika kwa ndodo ndi mtundu wa mutu wa msomali.Bokosi ndi gawo logulira.
Pali mitundu iwiri ya zomangira zomangira matabwa, imodzi ndi yowongoka ndipo inayo ndi yopingasa, yomwe ili yoyenera mawonekedwe amtundu wa wononga mutu.Komanso, pali dalaivala wapadera anaika pa kubowola uta, amene ali oyenera kutsitsa ndi kutsitsa zazikulu matabwa zomangira.Ndi yabwino komanso yopulumutsa ntchito.
