yini umehluko phakathi kwe-metric threaded rod ne-British and American thread rod?

I-Metric thread rodfuthiInduku yaseBritish Americanzingamazinga amabili ahlukene okukhiqiza intambo. Umehluko phakathi kwabo ubonakala ikakhulukazi endleleni yokumelela usayizi, inombolo yezintambo, i-bevel angle kanye nobubanzi bokusetshenziswa. Ekwenziweni ngomshini, kuyadingeka ukukhetha indinganiso yentambo efanele ngokuya ngesimo esithile.

1. Imuphi umehluko omkhulu phakathi kwe-metric stud bolt ne-British kanye ne-American stud bolt?

Ibhawodi ye-metric studyaduma eFrance, futhi izici zayo ukuthi isebenzisa amamilimitha njengamayunithi, inezintambo ezimbalwa, futhi ine-engeli ye-bevel engu-60 degrees. IIbhawodi ye-stud yaseBrithani neyaseMelikayadabuka e-United Kingdom nase-United States, futhi izici zayo ukuthi isebenzisa amayintshi njengamayunithi, inezintambo eziningi, futhi ine-engeli ye-bevel engu-55 degrees.

2. Uyini umehluko phakathi kwe-metric threaded rod din975 kanye ne-British kanye ne-American threaded rod din975 osayizi bentambo?

Ngokuya ngosayizi, usayizi wezintambo ze-metric rod din975 uvezwa ngokobubanzi (mm) kanye nephitshi (mm), kuyilapho imicu yaseBrithani neyaseMelika i-din975 ivezwa ngokosayizi (intshi), iphimbo, nohlelo lwentambo ( inombolo yemicu).

Isibonelo, intambo engu-M8 x 1.25, lapho okuthi “M8″ imele ububanzi obungu-8 mm, futhi “1.25″ imele ibanga elingu-1.25 mm phakathi kwentambo ngayinye. Ngemicu yaseBrithani neyaseMelika, i-1/4 -20 UNC imele usayizi wentambo engu-1/4 intshi, iphimbo lemicu engama-20 iyintshi ngayinye, futhi i-UNC imele indinganiso kazwelonke yohlamvu olumahhadla yomucu.

3. Ububanzi bokusetshenziswa komkhiqizi we-metric threaded rod kanye nomkhiqizi wezinduku ezinentambo zaseBrithani nezaseMelika

Njengoba umkhiqizi we-metric threaded rod enezintambo ezimbalwa nama-bevel amancane, akulula ukulumana ngesivinini esikhulu, ngakho-ke izingxenye eziningi eziwumshini zisebenzisa imicu yemethrikhi. Izintambo zaseBrithani nezaseMelika zivame ukusetshenziswa ezikhathini ezithile ezikhethekile, njengezintambo zamapayipi ezijwayelekile zaseMelika.

4. Ukuguqulwa kokucaciswa

Njengoba imicu yemethrikhi kanye nemicu yaseBrithani neyaseMelika kungamazinga amabili ahlukene okukhiqiza, ukuguqulwa kuyadingeka. Izindlela zokuguqula ezivamile zihlanganisa ukusebenzisa amathuluzi okuguqula noma ukubhekisela kumathebula okuguqula.
