1. Okokuqala, jonga i-engile yomsonto
Eyona ndlela ichanekileyo kukulinganisa nge-thread gauge. I-60° yeyomgangatho waseMelika, kwaye i-55° yeyomgangatho waseBritane.
Ukuba akukho zixhobo zifumanekayo, kwiintambo zepayipi, ungajonga indlela yokutywina: Iintambo ze-NPT ezisemgangathweni zaseMelika zihlala zitywina nge-taper yentambo ngokwayo; Iintambo ze-BSP ezisemgangathweni zaseBritane (ezifana ne-BSPT, i-BSPP) zine-engile yentambo engama-55°, kwaye iintambo ze-BSPP ezihambelanayo kufuneka zixhomekeke kwiringi yokutywina ukuze zitywine.
2. Iiparameter zokujonga ezibalulekileyo (ubukhulu kunye ne-TPI)
Kwizinto zokubopha ezifana neebholiti kunye neenati ezineentambo ezidityanisiweyo, emva kokulinganisa ububanzi obukhulu (ububanzi bangaphandle bomsonto wangaphandle / ububanzi bangaphakathi bomsonto wangaphakathi), eyona nto ibalulekileyo kukubala inani lemisonto nge-intshi (TPI), uze ujonge kwincwadana yemiyalelo eqhelekileyo.
Kwimisonto yepayipi, ukongeza ekulinganiseni ubukhulu, kufuneka umisele nokuba yintambo enciphileyo (njenge-NPT, i-BSPT) okanye yintambo ethe tye (njenge-BSPP), kunye nendlela yokutywina.
3. Jonga ngqo ikhowudi eqhelekileyo
Ukuba kukho uphawu oluqhelekileyo kwinxalenye (efana ne-UNC, i-UNF, i-BSW, i-BSF, i-NPT, i-BSPP, njl.njl.), esi sesona siseko sithembekileyo.
Landelela umva ukuya kumthombo
Intambo eqhelekileyo yaseBritane yavela kwintambo kaJoseph Whitworth ye-55-degree Whitworth ngo-1841;
Intambo esemgangathweni yaseMelika yacetywa nguWilliam Sellers ngo-1864 njengentambo ye-degrees ezingama-60.
Enyanisweni, ngexesha leMfazwe Yehlabathi yesiBini, imigangatho yaseBritane neyaseMelika yabangela ubunzima obukhulu ekutshintshiselaneni ngezixhobo phakathi kwemikhosi yamaAllied. Ngoko ke, ngo-1948, i-United States, i-United Kingdom, kunye neKhanada zaphuhlisa umgangatho odibeneyo (UNC/UNF).
Okubangel’ umdla kukuba, ukususela ngo-1961, imibutho yamazwe ngamazwe efanelekileyo yamkela inkcazo yemisonto esemgangathweni yaseBritane, i-ISO R 228. Ngoku ke, umsonto waseBritane ngumgangatho onzima osetyenziswa kwihlabathi liphela.
