Njengento ebalulekileyo kuqhagamshelo lomatshini, ukhetho lweeparamitha ze-fasteners lubalulekile ekuqinisekiseni uzinzo kunye nokhuseleko loqhagamshelo.
1. Igama leMveliso (Esemgangathweni)
Igama lemveliso ye-fastener linxulunyaniswa ngokuthe ngqo nesakhiwo sayo kunye nemeko yokusetyenziswa. Kwiifasteners ezithobela imigangatho ethile, ukuleyibhela inombolo esemgangathweni kunokubonakalisa ngokuchanekileyo ukuyila kunye nokusebenza kwazo. Ukungabikho kwemigangatho ecacileyo, iinxalenye ezingezizo eziqhelekileyo (iindawo ezingezizo eziqhelekileyo) zifuna imizobo ecacileyo ukubonisa imilinganiselo kunye nemilo yazo.
2. Iinkcukacha
Ukucaciswa kwe-fasteners ngokuqhelekileyo kuqulethwe ngamacandelo amabini: ububanzi bentambo kunye nobude be-screw. Iisistim zemetric kunye neMelika zezona nkqubo zimbini zokuchaza. Izikrufu ze-Metric ezifana ne-M4-0.7x8, apho i-M4 imele intambo yangaphandle ye-4mm, i-0.7 imele i-pitch, kwaye i-8 imele ubude be-screw. Izikrufu zaseMelika ezifana no-6 # -32 * 3/8, apho u-6 # emele i-diameter yangaphandle yomsonto, i-32 imele inani lemisonto nge-intshi yobude bomsonto, kwaye u-3/8 bubude besikrufu.
3. Izinto eziphathekayo
Izinto zokuqinisa i-fasteners zigqiba amandla azo, ukuxhathisa ukubola, kunye nobomi benkonzo. Izinto eziqhelekileyo ziquka i-carbon steel, insimbi engenasici, isinyithi esingenasici, ithusi, i-aluminium, njl. Kubalulekile ukukhetha izinto ezifanelekileyo ngokusekwe kwimeko yesicelo kunye neemfuno zokusebenza.
4. Inqanaba lamandla
Kwiintsimbi ze-carbon steel fasteners, ibakala lamandla libonisa amandla abo okuqina kunye namandla emveliso. Amanqanaba aqhelekileyo abandakanya i-4.8, 5.8, 6.8, 8.8, 10.9, 12.9, njl. Izikrufu zamandla aphezulu, njengemveliso yebanga le-8.8 okanye ngaphezulu, ngokuqhelekileyo zifuna ukucima kunye nokufudumala unyango lokufudumala ukuphucula iimpawu zabo zomatshini.
5. Unyango lomphezulu
Unyango lomphezulu lujolise ikakhulu ekwandiseni ukuxhathisa ukubola kunye ne-aesthetics ye-fasteners. Iindlela eziqhelekileyo zokucutshungulwa ziquka ukwenza mnyama, ukwenza igalvanizing (ezifana neblue namhlophe zinc, white zinc, etc.), copper plating, nickel plating, chrome plating, njl njl. ubomi benkonzo yeefasteners.
Ngamafutshane, xa ukhetha iziqhoboshi, kuyafuneka ukuba kuqwalaselwe ngokubanzi izinto ezifana negama lemveliso (umgangatho), iinkcukacha, izixhobo, umgangatho wamandla, kunye nonyango lomphezulu ukuqinisekisa ukuba ziyahlangabezana neemfuno zokusetyenziswa kwaye zisebenza kakuhle kunye nobomi.
