Izindinganiso ezisetshenziswa kakhulu yilezi ezilandelayo:
Izinga Likazwelonke le-GB-China (Izinga Likazwelonke)
Izinga Likazwelonke le-ANSI-American (Izinga LaseMelika)
I-DIN-Izinga Likazwelonke LaseJalimane (Izinga LaseJalimane)
Izinga le-ASME-American Society of Mechanical Engineers
I-JIS-Izinga Likazwelonke LaseJapane (Izinga LaseJapane)
I-BSW-Izinga Likazwelonke LaseBrithani
Ngaphezu kobukhulu obuthile obuyisisekelo, njengobukhulu bekhanda kanye nohlangothi oluphambene lwekhanda, ingxenye ehluke kakhulu yezindinganiso ezishiwo zezikulufo yintambo. Izintambo ze-GB, DIN, JIS, njll. zonke zise-MM (millimeters), ezibizwa ngokuthi izintambo ze-metric. Izintambo ezifana ne-ANSI, ASME, zingama-intshi futhi zibizwa ngokuthi izintambo ezijwayelekile zaseMelika. Ngaphandle kwezintambo ze-metric kanye nezintambo zaseMelika, kukhona ne-BSW-British standard, kanti izintambo nazo zingama-intshi, ezaziwa kakhulu ngokuthi izintambo zaseWhitworth.
Intambo ye-metric iku-MM (mm), kanti i-angle yayo ye-cusp ingu-60 degrees. Zombili izintambo zaseMelika neze-Imperial zilinganiswa ngamasentimitha. I-angle ye-cusp yentambo yaseMelika nayo ingu-60 degrees, kanti i-angle ye-cusp yentambo yaseBrithani ingu-55 degrees. Ngenxa yamayunithi ahlukene okulinganisa, izindlela zokumelela izintambo ezahlukene nazo zihlukile. Isibonelo, i-M16-2X60 imelela intambo ye-metric. Kusho ngokuqondile ukuthi ububanzi obujwayelekile besikulufu bungu-16MM, i-pitch ingu-2MM, kanti ubude bungu-60MM. Esinye isibonelo: 1/4-20X3/4 isho intambo yesistimu yaseBrithani. Incazelo yayo ethize ukuthi ububanzi obujwayelekile besikulufu bungu-1/4 intshi (intshi eyodwa = 25.4MM), kunamazinyo angu-20 ku-intshi eyodwa, kanti ubude bungu-3/4 intshi. Ngaphezu kwalokho, uma ufuna ukukhombisa izikulufu ezenziwe eMelika, i-UNC ne-UNF zivame ukungezwa ngemuva kwezikulufu ezenziwe eBrithani ukuhlukanisa phakathi kwezintambo eziqinile ezenziwe eMelika kanye nezintambo ezincane ezenziwe eMelika.
I-Yihe enterprise yinkampani egxile ekukhiqizeni izikulufo ze-amchine ezenziwe e-US ze-ANSI, isikulufo somshini we-BS, i-bolt corrugated, indlcuidng 2BA, 3BA, 4BA; izikulufo zomshini ezenziwe eJalimane i-DIN (DIN84/ DIN963/ DIN7985/ DIN966/ DIN964/ DIN967); i-GB Series kanye nezinye izinhlobo zemikhiqizo ejwayelekile nengeyona ejwayelekile njengezikulufo zomshini nazo zonke izinhlobo zezikulufo zomshini wethusi.
