Imigangatho esetyenziswa kakhulu yile ilandelayo:
Umgangatho weSizwe we-GB-China (uMgangatho weSizwe)
Umgangatho weSizwe we-ANSI-American (uMgangatho waseMelika)
Umgangatho weSizwe we-DIN-German (Umgangatho waseJamani)
Umgangatho we-ASME-American Society of Mechanical Engineers
I-JIS-Umgangatho weSizwe waseJapan (Umgangatho waseJapan)
I-BSW-uMgangatho weSizwe waseBritane
Ukongeza kumlinganiselo othile osisiseko, njengobukhulu bentloko kunye necala elichaseneyo lentloko, eyona nxalenye yahlukileyo yemigangatho ekhankanyiweyo yezikrufu yintambo. Imisonto ye-GB, i-DIN, i-JIS, njl. yonke ikwi-MM (iimilimitha), ezibizwa ngokuba yimisonto ye-metric. Imisonto efana ne-ANSI, i-ASME, ikwii-intshi kwaye ibizwa ngokuba yimisonto esemgangathweni yaseMelika. Ngaphandle kwemisonto ye-metric kunye nemisonto yaseMelika, kukwakho nomgangatho we-BSW-British, kwaye imisonto ikwakwii-intshi, eyaziwa ngokuba yimisonto yaseWhitworth.
Umsonto we-metric ukwi-MM (mm), kwaye i-engile yawo ye-cusp yi-60 degrees. Zombini imisonto yaseMelika neye-Imperial ilinganiswa ngee-intshi. I-engile ye-cusp yomsonto waseMelika nayo yi-60 degrees, ngelixa i-engile ye-cusp yomsonto waseBritane yi-55 degrees. Ngenxa yeeyunithi ezahlukeneyo zokulinganisa, iindlela zokumelwa kwemisonto eyahlukeneyo nazo zahlukile. Umzekelo, i-M16-2X60 imele umsonto we-metric. Ithetha ngokukodwa ukuba ububanzi obuqhelekileyo be-screw yi-16MM, i-pitch yi-2MM, kwaye ubude yi-60MM. Omnye umzekelo: 1/4-20X3/4 ithetha umsonto wenkqubo yaseBritane. Intsingiselo yayo ethile kukuba ububanzi obuqhelekileyo be-screw yi-1/4 intshi (intshi enye = 25.4MM), kukho amazinyo angama-20 kwi-intshi enye, kwaye ubude yi-3/4 intshi. Ukongeza, ukuba ufuna ukubonisa izikrufu ezenziwe eMelika, i-UNC kunye ne-UNF zihlala zongezwa emva kwezikrufu ezenziwe eBritane ukwahlula phakathi kwemisonto erhabaxa eyenziwe eMelika kunye nemisonto emincinci eyenziwe eMelika.
I-Yihe enterprise yinkampani egxile ekuveliseni izikrufu ze-amchine ezenziwe e-US ze-ANSI, izikrufu zomatshini ze-BS, i-bolt corrugated, indlcuidng 2BA, 3BA, 4BA; izikrufu zomatshini ezenziwe eJamani ze-DIN (DIN84/ DIN963/ DIN7985/ DIN966/ DIN964/ DIN967); i-GB Series kunye nezinye iintlobo zeemveliso ezisemgangathweni nezingezizo ezisemgangathweni ezifana nezikrufu zomatshini kunye nazo zonke iintlobo zezikrufu zomatshini wobhedu.
