Uyini umehluko phakathi kwesigamu se-12.9 enomugqa onomugqa futhi usindile ngokugcwele induku eyi-12,9?

I-Threaded Rood DIN 975 Steel 12.9 Inemicu engxenyeni yobude be-bolt, kanti enye ingxenye ayinantambo. Ama-bolts agcwele anentambo anemicu ebheke yonke ubude be-bolt. Umehluko wesakhiwo phakathi kwalezi zinhlobo ezimbili zama-bolts anquma uhla lwazo lokusebenza nokuqinisa ukusebenza lapho kusetshenziswa.

Izinduku ezinohlonze ezifakwe kakhulu zisetshenziselwa kakhulu imishini yokuqinisa kanye nemishini ethwala imithwalo ye-lateral, exhuma imishayo yensimbi, ukuxhuma imishayo, imishayo, kanye nenzuzo yazo ukuthi kulula ukunqabalala futhi kuthathe indawo. Izinduku ezigcwele ezigcwele zisetshenziselwa kakhulu ukuxhuma imishini ethwala imithwalo emide, njengokuxhuma izinjini zezimoto kanye nezisekelo zezimoto, ukuxhuma ujantshi wesitimela, njll, futhi inzuzo yazo ukuthi banamandla amakhulu okuqinisa.

Lapho ufaka induku enohhafu, ingxenye efakwe ngo-pure kufanele ilungiswe ngani, bese iBolt kufanele ijikeleze ukuze iqinise ingxenye ebekiwe ukushayela ingxenye yemishini ukuze iqinise. Lapho ufaka induku egcwele egcwele, kuyadingeka ukuphoqa imicu ngalo lonke ubude be-bolt kule ngxenye ukuze uqinisekise amandla okuqinisa.

Kunomehluko osobala phakathi kwezinduku ezinama-harf-threaded kanye nezinduku ezigcwele ngokugcwele ngokwesakhiwo, uhla lwesicelo nendlela yokufaka. Lapho ukhetha uhlobo lwenduku, kuyadingeka ukuthi ukhethe uhlobo olufanele ngokuya ngezidingo ezithile zokusetshenziswa kanye nendawo yokufaka ukuze uqinisekise ukusebenza okuzinzile kwezingxenye zomshini.
