Uma kukhulunywa ngezibambo, amabhawodi ayisithupha ayindlela evamile yokubamba izinto ndawonye. Kodwa-ke, amabhawodi ayisithupha afika ngezindlela ezahlukene ngokwezindinganiso ezahlukene. Sizohlola umehluko phakathi kwamabhawodi ayisithupha aseMelika namabhawodi avamile ayisithupha kanye nokusetshenziswa kwawo okuhlukahlukene empilweni yansuku zonke.
Eminye yemimehluko emikhulu phakathi kwama-bolts e-hexagon aseMelika nama-bolts ajwayelekile angaphakathi e-hexagon ihlanganisa:
Izindinganiso zokukhiqiza: Amabhawodi e-hexagon aseMelika akhiqizwa ngokwezindinganiso ezithile ze-ASTM ukuqinisekisa ukuvumelana nokulawulwa kwekhwalithi. Kodwa-ke, ayikho indinganiso enjalo yamabhawodi e-hexagon avamile, futhi inqubo yokukhiqiza ingase ihluke.
Imininingwane yezinto ezibonakalayo: Amabhawodi e-hexagon aseMelika avame ukuba nemininingwane yezinto ezibonakalayo ezicacile, njengezinhlobo ezithile zensimbi noma ezinye izinhlobo ze-alloy. Amabhawodi e-hexagon ajwayelekile angenziwa ngezinto ezahlukahlukene, kodwa ikhwalithi namandla kungase kuhluke.
Ukunemba kobukhulu: Amabhawodi e-hexagon aseMelika akhiqizwa ngokunemba kobukhulu okunembile ukuze afakwe kahle ezingxenyeni ezijwayelekile. Amabhawodi e-hexagonal avamile angase abe nezinguquko ezincane ngobukhulu, okungase kuthinte ukuhambisana kwawo kwezinye izinhlelo zokusebenza.
Ukusetshenziswa kwama-American hexagonal bolts empilweni yansuku zonke: ngenxa yokuthembeka kwayo kanye nemininingwane ejwayelekile, isetshenziswe kabanzi ezimbonini ezahlukahlukene nasezigcawini zansuku zonke. Ifaka phakathi imishayo, amakholomu, kanye nozimele. Banikeza ukuxhumana okuphephile ukuqinisekisa ukuzinza kwesakhiwo kanye nobuqotho.
Imboni yezimoto: idlala indima ebalulekile ekuhlanganiseni izingxenye zezimoto njengezinjini, i-chassis kanye nezinhlelo zokumiswa. Lawa mabholidi anikeza amandla nokuqina okudingekayo ukuze imoto isebenze ngokuphephile nangokuthembekile.
Imishini nemishini: Amabhawodi e-hexagon aseMelika asetshenziswa ekwakhiweni kwemishini, imishini, kanye nezinto zikagesi ukuze kuhlanganiswe izingxenye. Qinisekisa ukusebenza okuvamile futhi uvimbele ukuxega ngesikhathi sokusebenza.
Ukuhlanganiswa kwefenisha: hlinzeka ngokuxhumeka okuqinile nokuzinzile ukuqinisekisa ukuqina kwezingxenye zefenisha.
Ngamafuphi, amabhawodi ekhanda asezingeni eliphakathi aseMelika ahlukile kumabhawodi ekhanda ajwayelekile ayisithupha ngoba ahambisana nezindinganiso ezithile zokukhiqiza ze-ASTM, imininingwane yezinto ezibonakalayo kanye nokunemba kobukhulu. Futhi asetshenziswa kabanzi ezimbonini ezahlukahlukene kanye nokuphila kwansuku zonke, okuhlanganisa ukwakhiwa, izimoto, imishini kanye nokuhlanganiswa kwefenisha. Ukuqonda umehluko kanye nokusetshenziswa kwala mabhawodi kungakusiza ukuthi wenze izinqumo ezinolwazi lapho ukhetha izikhonkwane ezifanele zamaphrojekthi noma izidingo ezithile.
