Kev piav qhia ntau lawm
Lub ntsiab daim ntawv thov ntawm steel qauv ntsia liaj qhov rooj txiv ntoo yog nyob rau hauv steel qauv engineering project mus cuag cov nodes ntawm steel phaj tuab steel qauv. Zoo dua fastening yam ntxwv, siv rau steel qauv thiab engineering tej yaam num, ib tug fastening nyhuv. Hauv cov qauv hlau dav dav, qhov yuav tsum tau muaj cov qauv steel bolts yog siab dua 8.8 qib, kuj tseem muaj 10.9,12.9. Tag nrho cov no yog high-toughness steel qauv bolts. Qee zaum cov bolts ntawm cov qauv hlau tsis siv cov txheej txheem electroplating, tab sis siv cov xim thawj tuaj yeem ua tau.
Steel qauv bolts tau muab faib ua torsion-shear siab zog bolts thiab loj hexagonal taub hau siab zog bolts. Loj hexagonal siab zog ntsia liaj qhov rooj belongs rau lub siab toughness theem ntawm dav dav screws, torsional shear siab zog ntsia liaj qhov rooj yog ib qho kev txhim kho version ntawm loj hexagonal siab zog ntsia liaj qhov rooj, thiaj li yuav zoo dua engineering siv.
