Isikhuhli sokuziqhuba sisiseko somatshini, esifuneka kakhulu. Ngokwesiqhelo, ii-bolts, i-screws, i-rivets, njl njl, ukuze kuqinisekiswe ukhuseleko okanye ngokubanzi akufuneki uqwalasele ifuthe lobushushu, indawo embi okanye ezinye iimeko zomsebenzi eziyingozi. Izixhobo eziqhelekileyo ziyintsimbi yecarbon, yintsimbi yealloy ephantsi kunye neentsimbi ezingenabunzima. Kodwa kumaxesha athile, izixhobo ze-fastener kufuneka zihlangabezane neemeko zokuqina okukhulu okanye amandla aphezulu, zininzi i-iron stainless kunye ne-Ultra ephezulu yamandla angenasici. Ezi ngxaki zintandathu zilandelayo kufuneka ziqwalaselwe xa usebenzisa kunye nokugcina ucingo lomsila wokumba:
1. Inkqubo yokuhambisa i-wire ye-waya yokutsala ingxamiseke kakhulu kwaye kufuneka uqaphele kakhulu. Ngexesha lenkqubo, kuya kubakho iintsalela kumphezulu wocingo lomsila wokumba. Eli nyathelo kukukhupha emva kokuba isicocekile isilivere sele ihlanjwe.
2. Ngexesha lenkqubo yokuvavanywa, isitaki kufuneka sidityaniswe, ngaphandle koko i-oxidation encinci iya kwenzeka kwi-oyile yokucima.
3. Intsalela ye-phosphide emhlophe iya kuvela kumphezulu wezikrufu zamandla aphezulu, ibonisa (inqaku 1) ukuba uhlolo alunononophelo ngokwaneleyo ngexesha lokusebenza. 4. Into emnyama kumphezulu weenxalenye ivelisa ukusetyenziswa kweekhemikhali, okubonisa ukuba unyango lobushushu alwenziwe kakuhle kwaye intsalela ye-alkali kumphezulu ayikasuswa ngokupheleleyo.
5. Amanqanaba asemgangathweni aya kuba rust kwi-rinsing, kwaye amanzi asetyenziselwa i-rinsing kufuneka atshintshwe rhoqo.
6. Ukugcwala okugqithisileyo kubonisa ukuba ioyile yokucima isetyenziselwe ixesha elide, kwaye kufuneka yongezwe okanye itshintshwe.
