Ntle le tekanyo e itseng ea motheo, joalo ka botenya ba hlooho le lehlakore le fapaneng la hlooho, karolo e fapaneng ka ho fetisisa ea litekanyetso tse boletsoeng bakeng sa li-screw ke khoele. Likhoele tsa GB, DIN, JIS, jj. kaofela li ka MM (limilimithara), tse bitsoang likhoele tsa metric hammoho. Likhoele tse kang ANSI, ASME, li ka lisenthimithara 'me li bitsoa likhoele tse tloaelehileng tsa Amerika. Ntle le likhoele tsa metric le likhoele tsa Amerika, ho boetse ho na le tekanyetso ea BSW-British, 'me likhoele le tsona li ka lisenthimithara, tse tsejoang ka tloaelo e le likhoele tsa Whitworth.
Khoele ea metric e ka MM (mm), 'me sekhutlo sa eona sa cusp ke likhato tse 60. Likhoele tsa Amerika le tsa Imperial ka bobeli li lekanngoa ka lisenthimithara. Sekhutlo sa cusp sa khoele ea Amerika le sona ke likhato tse 60, ha sekhutlo sa cusp sa khoele ea Brithani e le likhato tse 55. Ka lebaka la li-unit tse fapaneng tsa tekanyo, mekhoa ea boemeli ba likhoele tse fapaneng le eona e fapane. Mohlala, M16-2X60 e emela khoele ea metric. E bolela ka ho khetheha hore bophara ba nominee ba screw ke 16MM, bophahamo ke 2MM, 'me bolelele ke 60MM. Mohlala o mong: 1/4-20X3/4 e bolela khoele ea tsamaiso ea Brithani. Tlhaloso ea eona e tobileng ke hore bophara ba nominee ba screw ke 1/4 inch (inch e le 'ngoe = 25.4MM), ho na le meno a 20 ho inch e le 'ngoe, 'me bolelele ke 3/4 inch. Ho phaella moo, haeba u batla ho bontša li-screw tse entsoeng Amerika, UNC le UNF hangata li eketsoa ka mor'a li-screw tse entsoeng Brithani ho khetholla pakeng tsa likhoele tse mahoashe tse entsoeng Amerika le likhoele tse ntle tse entsoeng Amerika.
Yihe enterprise ke khamphani e ikhethang ka ho hlahisa dikurufu tsa amchine tse entsweng Amerika tsa ANSI, dikurufu tsa mochini wa BS, dikurufu tsa bolt tse kobehileng, tse entsweng ka 2BA, 3BA, 4BA; dikurufu tsa mochini tse entsweng Jeremane tsa DIN (DIN84/ DIN963/ DIN7985/ DIN966/ DIN964/ DIN967); GB Series le mefuta e meng ya dihlahiswa tse tloaelehileng le tse seng tsa maemo a hodimo tse kang dikurufu tsa mochini le mefuta yohle ya dikurufu tsa mochini wa koporo.
