Amazinga asetshenziswa kakhulu yilawa alandelayo:
I-GB-China National Standard (Izinga Likazwelonke)
I-ANSI-American National Standard (American Standard)
I-DIN-German National Standard (I-German Standard)
I-ASME-American Society of Mechanical Engineers Standard
I-JIS-Japanese National Standard (I-Japanese Standard)
I-BSW-British National Standard
Ngaphezu kobukhulu obuthile obuyisisekelo, obufana nokujiya kwekhanda kanye nohlangothi olubhekene nekhanda, ingxenye ehluke kakhulu yezindinganiso ezishiwo zezikulufi intambo.Imicu ye-GB, DIN, JIS, njll. yonke iku-MM (amamilimitha) , njengeqoqo elibizwa ngokuthi uchungechunge lwemethrikhi.Imicu efana ne-ANSI, ASME, ingamayintshi futhi ibizwa ngokuthi imicu evamile yaseMelika.Ngaphandle kwezintambo zemethrikhi nemicu yaseMelika, kukhona futhi izinga le-BSW-British, futhi imicu iphinde ibe ngama-intshi, eyaziwa ngokuthi izintambo zaseWhitworth.
Intambo yemethrikhi iku-MM (mm), futhi i-cusp angle yayo ingu-60 degrees.Kokubili imicu yaseMelika kanye neye-Imperial ikalwa ngamayintshi.I-cusp angle yentambo yaseMelika nayo ingamadigri angu-60, kuyilapho i-cusp angle yentambo yaseBrithani ingamadigri angu-55.Ngenxa yamayunithi ahlukene okulinganisa, izindlela zokumelela izintambo ezihlukahlukene nazo zihlukile.Isibonelo, i-M16-2X60 imele intambo ye-metric.Kusho ngokuqondile ukuthi ububanzi obujwayelekile besikulufu ngu-16MM, iphimbo lingu-2MM, kanti ubude bungu-60MM.Esinye isibonelo: 1/4-20X3/4 isho intambo yesistimu yaseBrithani.incazelo yalo ethize ubukhulu besilinganiso se-screw ingu-1/4 intshi (intshi eyodwa=25.4MM), kukhona amazinyo angu-20 kuyintshi eyodwa, futhi ubude buyi-intshi engu-3/4.Ukwengeza, uma ufuna ukukhombisa izikulufu ezenziwe eMelika, i-UNC ne-UNF kuvame ukungezwa ngemva kwezikulufu ezenziwe eBrithani ukuze kuhlukanise phakathi kwezintambo ezimahhadla ezenziwe eMelika kanye nemicu emihle eyenziwe yaseMelika.
I-Yihe enterprise yinkampani esebenza ngokukhethekile ekukhiqizeni izikulufu ze-amchine ezenziwe e-US, i-ANSI, isikulufu somshini we-BS, ibholithi eyenziwe ngothayela, indlcuidng 2BA, 3BA, 4BA;Izikulufu zomshini ezenziwe eJalimane i-DIN (DIN84/ DIN963/ DIN7985/ DIN966/ DIN964/ DIN967);I-GB Series nezinye izinhlobo zemikhiqizo evamile nengajwayelekile njengezikulufu zomshini nazo zonke izinhlobo zezikulufu zomshini wethusi.
