Izinto zokubopha ziyizingxenye ezibalulekile ekwenziweni kwemishini nobunjiniyela, ezisetshenziselwa ngokuyinhloko ukuxhuma nokuvikela izingxenye ezimbili noma ngaphezulu, okuqinisekisa ukuzinza nokuthembeka kwesakhiwo. Afika ngezinhlobo eziningi ezahlukene futhi asetshenziswa kakhulu emikhakheni ebalulekile, okuhlanganisa ukukhiqizwa kwezimboni, ezokwakha, ezezimoto, kanye ne-aerospace.
Ngokwesakhiwo, izinsimbi ngokuvamile zihlanganisa ikhanda kanye ne-shank, ezifinyelela ukuqiniswa ngemicu noma ezinye izakhiwo zemishini. Izibophelelo ezivame kakhulu zihlanganisa amabhawudi, izikulufu, amantongomane, amawasha, nama-rivets. Amabhawudi namantongomane asetshenziswa ndawonye, adinga{2}}izimbobo ezimbozwe ngaphambili ezingxenyeni ezixhumayo futhi kuqiniswe amantongomane ukuze kuvikeleke ukuxhumana. Izikulufu zingagqunywa ngqo{4}ezimbotsheni ezinemicu noma zibe into, kuqede isidingo samantongomane engeziwe. Amawasha asabalalisa ukucindezela ukuvimbela ukuxega noma ukulimala endaweni yokuxhuma. Ama-Rivets, avikeleke ngokuwohloka, afanele ukuxhumana okungunaphakade,-okungakhipheki.
Ukukhethwa kwezinto zokubopha kunomthelela ngokuqondile ekusebenzeni kwazo nezinhlelo zokusebenza ezisebenzayo. Izinsimbi ezijwayelekile ze-carbon steel fasteners zinikeza izindleko eziphansi namandla alinganiselwe, okwenza zisetshenziswe kabanzi ekusetshenzisweni kwezimboni ezijwayelekile. Izibophelelo zensimbi engagqwali zinikeza ukumelana nokugqwala okuhle kakhulu futhi zifanele ukusetshenziswa ezindaweni ezinomswakama noma ezidla amakhemikhali. Izinsimbi zensimbi noma i-titanium alloy fasteners zisetshenziswa-emandleni aphezulu,{4}}ezindaweni zokushisa eziphezulu noma ezindaweni ezinzima ezifana ne-aerospace. Ukwelashwa okungaphezulu okufana nokufaka i-galvanizing, i-phosphating, noma i-Dacromet coating kungathuthukisa ukumelana nokugqwala nempilo yesevisi yezinsimbi.
Emkhiqizweni wezimboni, ukumiswa kwe-fastener kubalulekile. Izindinganiso zamazwe ngamazwe (ezifana ne-ISO), izindinganiso zikazwelonke (ezifana ne-GB ne-ANSI), kanye namazinga omkhakha aqinisekisa ukushintshashintsha kanye nokuvumelana kwendawo yonke yezibophelelo, kwehlisa kakhulu izindleko zokuklama nezokunakekela. Ngokuthuthukiswa kokukhiqiza okukhaliphile, ubuchwepheshe obusha bokusheshisa, obufana{2}}namandla aphezulu,{3}}ukuzikhiya, kanye nesisindo esincane, ziyavela, ziqhubekisela phambili inqubekelaphambili{4}}embonini yokukhiqiza imishini ephezulu.
Njenge "isixhumanisi" sokuxhumeka kwemishini, izinsimbi, nakuba zincane, zibalulekile, futhi ukwethembeka kwazo kuhlobene ngokuqondile nokusebenza okuphephile kwemishini. Ngokuzayo, ngokuthuthuka kwesayensi yezinto zokwakha kanye nobunjiniyela, izinto zokubopha zizoqhubeka zithuthukela ekusebenzeni okuphezulu nasekuhlakanipheni, zihlinzeka ngosekelo oluqinile lwezobuchwepheshe ezimbonini ezahlukahlukene.
