Xa kuziwa kwii-fasteners, iibholiti ezine-hexagonal lukhetho oluqhelekileyo lokubamba izinto kunye. Nangona kunjalo, i-hexagonal bolts iza ngeendlela ezahlukeneyo ngokwemigangatho eyahlukeneyo. Siza kuphonononga umahluko phakathi kweebholiti ze-hexagonal zaseMelika kunye neebholiti eziqhelekileyo ezinehexagonal kunye nokusetyenziswa kwazo okwahlukeneyo kubomi bemihla ngemihla.
Olunye ulwahlulo oluphambili phakathi kweebholiti zehexagon zaseMelika kunye neebholiti eziqhelekileyo zangaphakathi zehexagon ziquka:
Imigangatho yokuvelisa: Iibholiti ze-hexagon zaseMelika zenziwe ngokwemigangatho ethile ye-ASTM ukuqinisekisa ukuhambelana kunye nokulawula umgangatho. Nangona kunjalo, akukho mgangatho onjalo we-hexagon bolts eziqhelekileyo, kwaye inkqubo yokuvelisa inokwahluka.
Inkcazo yezinto eziphathekayo: Iibholiti ze-hexagon zaseMelika zihlala zineenkcazo ezibonakalayo ezicacileyo, njengamabakala athile ensimbi okanye ezinye i-alloys. Iibholiti eziqhelekileyo zehexagon zingenziwa kuluhlu olubanzi lwezixhobo, kodwa umgangatho kunye namandla anokwahluka.
Ukuchaneka komgangatho: Iibholiti zehexagon zaseMelika zenziwe ngokuchaneka okuchanekileyo komgangatho ukuze zifakwe ngokuchanekileyo kumacandelo asemgangathweni. Iibholiti eziqhelekileyo ze-hexagonal zinokuba neenguqu ezincinci kubungakanani, ezinokuchaphazela ukuhambelana kwazo kwezinye izicelo.
Ukusetyenziswa kweebholiti ze-American hexagonal kubomi bemihla ngemihla: ngenxa yokuthembeka kwayo kunye neenkcukacha ezisemgangathweni, isetyenziswe ngokubanzi kumashishini ahlukeneyo kunye nemiboniso yemihla ngemihla. Kubandakanya imiqadi, iikholamu, kunye nezakhelo. Babonelela ngoqhagamshelo olukhuselekileyo ukuqinisekisa uzinzo nokuthembeka kwesakhiwo.
Umzi-mveliso weemoto: udlala indima ebalulekileyo ekuhlanganiseni izinto zemoto ezinjengeenjini, itshisi kunye neenkqubo zokunqunyanyiswa. Ezi bholithi zibonelela ngamandla ayimfuneko kunye nokuqina kokusebenza okukhuselekileyo nokuthembekileyo kwesithuthi.
Oomatshini nezixhobo: Iibholiti zehexagon zaseMelika zisetyenziswa ekwenzeni izixhobo, oomatshini, kunye nezixhobo zombane ukuze kukhuselwe iinxalenye kunye. Qinisekisa ukusebenza okuqhelekileyo kwaye uthintele ukukhulula ngexesha lokusebenza.
Indibano yefenitshala: bonelela ngoqhagamshelo oluqinileyo noluzinzileyo ukuze kuqinisekiswe ukuqina kwamalungu efenitshala.
Isishwankathelo, i-American standard bolts hexagonal head bolts yahlukile kwi-head bolts yesiqhelo ye-hexagonal kuba ithobela imigangatho ethile yokwenziwa kwe-ASTM, ukucaciswa kwezinto kunye nokuchaneka komda. Kwaye isetyenziswa ngokubanzi kumashishini ahlukeneyo kunye nobomi bemihla ngemihla, kubandakanya ukwakhiwa, iimoto, oomatshini kunye nendibano yefenitshala. Ukuqonda iiyantlukwano kunye nokusetyenziswa kwezi bolts kunokukunceda wenze izigqibo ezinolwazi xa ukhetha izibophelelo ezifanelekileyo kwiiprojekthi okanye iimfuno ezithile.
