Thauj tog rau nkoj bolts yog qhov tseem ceeb txhim kho cov khoom siv hauv cov khoom siv kho tshuab, thiab lawv cov kev ua haujlwm cuam tshuam ncaj qha rau cov khoom ruaj khov thiab kev nyab xeeb ntawm cov khoom siv. Nkag siab cov muaj pes tsawg leeg thiab tsim cov txheej txheem ntawm thauj tog rau nkoj bolts yog qhov tseem ceeb rau cov neeg siv khoom lag luam kev lag luam kom raug thiab txhim kho cov khoom sib tw.
Thauj thauj tog rau nkoj Bolts feem ntau muaj cov shank, txiv ntoo, tshuab ntxhua, thiab kos cov khoom siv. Lub shank, thawj load - Cov kab hlau sib xyaw, xws li pob zeb loj, lossis thauj tog rau nkoj, kom haum ib puag ncig sib txawv. Cov txiv ntoo, xov rau lub shank, ruaj khov cov khoom siv nyob rau hauv qhov chaw thiab yuav tsum tau ua los ntawm tib yam lossis siab dua cov khoom siv ruaj khov los xyuas kom muaj ntev}} lub sij hawm ruaj khov. Lub tshuab ntxhua khaub ncaws faib cov khoom thauj ntawm cov ntsia liaj qhov rooj thiab tiv thaiv kev puas tsuaj rau cov khoom siv nto. Cov ntaub ntawv uas muaj cov pa roj carbon steel lossis stainless hlau.
Kev tsim khoom lag luam rau thauj tog rau nkoj bolts suav nrog cov ntaub ntawv txiav, xov, kev kho cua sov, thiab kev kho kom sov. Ua ntej, cov hlau txiav rau qhov tsim tau ntev thiab cov xov uas siv yog machined siv tshuab dhos lossis xov dov tshuab. Cov bolts ces yauv mus rau kev ua txhaum thiab npau taws kom lawv lub zog thiab lub zog tensile. Thaum kawg, los txhim kho corrosion tsis kam, lawv feem ntau galvanized, kub} dip galvanized, lossis txau nrog ove} Rust txheej kom tau raws li ntau yam.
Hauv kev lag luam thoob ntiaj teb kev lag luam, kev tsim kho ntawm thauj tog rau nkoj bolts yuav tsum nruj me ntsis cov qauv, xws li ISO lossis ASTM specifications. Cov chaw muag khoom yuav tsum tau kho lub ntsia liaj qhov rooj loj, khoom siv, thiab cov tshuaj nto raws li cov neeg siv khoom yuav tsum ua kom pom ntau yam nrog ntau yam khoom siv muaj ntau yam. Nkag siab cov ntsiab cai tsim kho thiab tsim cov ntsiab lus tseem ceeb ntawm thauj cov tuam txhab Bolts yuav tau txais cov duab hauv ntiaj teb, thiab txhim kho lawv cov duab tshaj lij thiab kev sib tw hauv kev ua lag luam thoob ntiaj teb.
