Kukhona i-ASTM A193 B7 ejwayelekile, i-A193 B8, i-A193 B8M, i-A193 B16 Thread Stud, engafinyelela izinga le-ASTM. Ngaleso sikhathi, imvamisa isetshenziswa ne-ASTM A194 2H hex nut. Zombili ziyatholakala lapha.
I-Tread Stud. Umsebenzi wesixhumanisi esingaguquki usetshenziselwa ukuxhuma umshini. Amabhawodi aphindwe kabili anentambo emikhawulweni yomibili, futhi isikulufu esiphakathi siwugqinsi futhi mncane. Ngokujwayelekile isetshenziswa emishinini yezimayini, ibhuloho, imoto, isithuthuthu, isakhiwo sensimbi ebhayela, umbhoshongo olengayo, isakhiwo sensimbi esinesikhathi eside kanye nezakhiwo ezinkulu.
I-1, isetshenziswa kakhulu emzimbeni omkhulu wezinto zokusebenza ezinkulu, ezidinga ukufaka izesekeli, njengesibuko, isihlalo sophawu lwemishini, ifreyimu yokunciphisa, njll. Ngalesi sikhathi, ukusetshenziswa kwamabhawudo anamakhanda amabili, umkhawulo owodwa wesikulufu ungene. umzimba oyinhloko, ukufakwa kokunamathiselwe ngemva komunye umkhawulo nge-nati, ngoba okunamathiselwe kuvame ukususwa, intambo izobe igqoke noma yonakaliswe, ukusetshenziswa kokushintshwa kwama-bolts anekhanda eliphindwe kabili kuyoba lula kakhulu. 2. Uma ubukhulu bomzimba oxhumayo bukhulu kakhulu futhi ubude be-bolt bude kakhulu, kuzosetshenziswa amabhawodi anamakhanda amabili. 3. Isetshenziselwa ukuxhuma amapuleti awugqinsi kanye nezindawo ezingalungile ukusebenzisa amabhawodi e-hex, njenge-truss yophahla lukakhonkolo, i-roof beam elenga izingxenye ezilengayo ze-monorail, njll.
