Lub tsev steel qauv bolts yog ib hom ntawm high-lub zog bolts thiab kuj yog ib hom ntawm qhov chaw txheem. Qhov kev ua tau nrawm dua tau zoo dua, thiab nws yog siv rau cov qauv hlau thiab kev tsim vaj tsev los ua kom muaj lub luag haujlwm ceev. Nyob rau hauv cov qauv hlau dav dav, qhov yuav tsum tau muaj cov qauv hlau qauv yog qib 8,8 lossis siab dua, thiab muaj qib 10.9 thiab 12.9, tag nrho cov no yog lub zog loj steel qauv bolts. Qee zaum cov bolts ntawm cov qauv steel tsis xav tau electroplating, thiab siv cov xim ntuj. tuaj yeem.
Cov qauv hlau bolts yog siv nyob rau hauv cov qauv steel tsim los txuas rau cov chaw sib txuas ntawm cov qauv steel qauv steel daim hlau.
Hlau qauv bolts tau muab faib ua torsion shear hom high-lub zog bolts thiab loj hexagonal high-lub zog bolts. Lub pob zeb loj hexagonal lub zog siab ua rau cov qib siab muaj zog ntawm cov screws zoo tib yam, thaum torsion shear hom high-strength bolts tau txhim kho hom hom loj hexagonal high-strength bolts rau kev tsim kho zoo dua.
Kev tsim kho ntawm cov qauv hlau qauv yuav tsum nruj nreem ua ntej thiab tom qab ntawd kawg kom nruj ntxiv. Thaum pib zawm ntawm steel qauv bolts yuav tsum muaj kev cuam tshuam hom hluav taws xob ciaj ntswj lossis cov hluav taws xob uas ntsaws tau kho lub ciaj ntswj; thiab qhov kawg txuas ntawm cov qauv steel bolts muaj qhov yuav tsum nruj, thiab qhov kawg zawm ntawm torsion shear hom steel qauv bolts yuav tsum siv torsion shear hom hluav taws xob ciav hlau, thiab torque hom hluav taws xob hlau yuav tsum tau siv rau qhov kawg ntswj torque hom steel qauv bolts.
Lub cev loj hexagonal steel qauv thooj cov ntsia liaj qhov rooj, ib lub txiv ntoo, thiab ob lub tshuab ntxhua khaub ncaws.
Lub torsion shear steel qauv ntsia liaj qhov rooj ntsia liaj qhov rooj, cov txiv ntoo, thiab cov ntxhua khaub ncaws.
