Kuyo nayiphi na inkqubo yokuvelisa okanye yokuhlanganisa, kodwa ngakumbi kwishishini lokwenziwa kwentsimbi, ukukhetha izibophelelo ezifanelekileyo kubalulekile. Kukho iintlobo ezininzi zeefasteners kwimarike, nganye yenzelwe isicelo esithile kunye nohlobo oluthile, kwaye ukwenza ukhetho olufanelekileyo kunokuphucula kakhulu ukuqina, amandla, kunye nenkangeleko yemveliso yakho. Ezi zikhokelo zilandelayo zinokukunceda ukhethe izibophelelo ezifanelekileyo kwiimfuno zakho.
Qwalasela iMpahla kunye nemekobume
Iimeko ezahlukeneyo zokusingqongileyo kunye nokusetyenziswa zineemfuno ezahlukeneyo zeziqhoboshi. Ngokomzekelo, kwiindawo ezingaphandle, izinto zokubopha kufuneka zibe nokuxhathisa kakuhle ekudlekeni ukuze zimelane nokukhukuliseka komoya, imvula, kunye neekhemikhali ezahlukeneyo. Kwiqondo lokushisa eliphezulu okanye kwiindawo zoxinzelelo oluphezulu, i-fasteners kufuneka ikwazi ukumelana neemeko ezinzima ukuqinisekisa ukuthembeka koqhagamshelwano.
Qonda umthwalo kunye neeMfuno zoxinzelelo
Ukuchaneka kobukhulu kunye neenkcukacha nazo ziyinto ebalulekileyo ekukhetheni i-fasteners. Umthwalo kunye nenqanaba loxinzelelo lwe-fastener zizinto eziphambili kwinkqubo yokukhetha. Iibholiti eziphakamileyo okanye i-fasteners ziyimfuneko kwizicelo ezinzima, ngelixa imithwalo elula ingafuna kuphela izikrufu eziqhelekileyo okanye iirivets. Qiniseka ukuba ujonga iinkcukacha zomthwalo xa ukhetha ukuphepha iingozi zokhuseleko.
Vavanya iintlobo ze-fasteners ukuhlangabezana neemfuno zendibano
Iindidi ezahlukeneyo ze-fasteners zingasetyenziselwa iinjongo ezahlukeneyo zokuhlanganisa. Ngokomzekelo, i-DIN 931 i-hexagonal head half-thread bolts isetyenziswa ngokubanzi kumatshini wokuvelisa, ukwakhiwa kunye nezinye iindawo; I-DIN 933 iibholiti ze-hexagonal zentloko zifanelekile kwizicelo ezifuna ukudibanisa intambo epheleleyo; I-DIN 6921 iibholiti ze-hexagonal flange zinendawo enkulu yokuxhasa kwaye inokubonelela ngemiphumo engcono yokuqinisa; I-DIN 934 i-hexagonal nuts isetyenziswe ngeebholiti; I-DIN 985 yamandongomane okutshixa inayiloni inokuthintela ukukhulula; I-DIN 439 yamantongomane amancinci angama-hexagonal afanelekile kwizihlandlo ezinendawo encinci; I-DIN 7991 i-hexagonal countersunk screws ineentloko ezitshona kwindawo enyukayo ukwenza umphezulu ubonakale usicaba; kukho kwakhona i-DIN 965 i-pan ye-screws ye-cross recessed head screws, i-DIN 125 i-washers flat, i-DIN 9021 i-washers enkulu, i-DIN127 i-spring washers, njl.
Cinga ngobuhle kunye nonyango lwangaphandle
Ukukhetha unyango olungaphezulu oluncedisayo okanye oluhambelana nezinto eziphathekayo kunokuzisa inkangeleko esulungekileyo kunye neyobuchule. Ngokukodwa kwizicelo eziveziweyo, i-aesthetics kunye ne-corrosion resistance inokwandiswa ngeendlela ezahlukeneyo zonyango olungaphezulu, olufana ne-zinc, i-nickel, okanye i-anodized coatings.
Qwalasela iindlela zokufakela kunye neendleko
Ukufakela ngokulula kunye neendleko zikwangumbandela obalulekileyo. Ngokomzekelo, i-self-tapping screws inokwenza lula inkqubo yokuhlanganisana kuba ayifuni u-pre-drilling. Izixhobo ezizenzekelayo zingasetyenziselwa i-rivets kunye ne-bolts, ezinokukhawuleza ukuhlanganisana kwimveliso yobuninzi, kodwa ziya kwandisa iindleko zokuqala.
Yenza ukhetho olufanelekileyo
Ukukhetha izibophelelo ezifanelekileyo kunokuqinisekisa ukuba imveliso ifezekisa ukusebenza kakuhle, ukuqina, kunye nenkangeleko. Ukukhethwa kwe-fastener efanelekileyo ekugqibeleni kunceda ukuphucula umgangatho jikelele kunye nokuthembeka kwemveliso egqityiweyo, ukuqinisekisa ukwaneliseka komsebenzisi kunye nentsebenziswano yexesha elide.
