Khoom Taw Qhia
ASTM A325 Hex Lub Taub Hau Screws yog qhov hnyav hex qauv bolts tsim los muab kev sib tw clamping quab yuam thiab muaj peev xwm thauj khoom siab rau kev sib txuas steel. Lawv yog siv nrog hnyav hex txiv ntseej thiab cov cuab yeej ntxhua khaub ncaws, kom ntseeg tau tias kev ua tau zoo hauv kev nro- tseem ceeb lossis shear- cov rooj sib txoos tseem ceeb.

FAQ
Q: ASTM A325 hex taub hau ntsia hlau siv rau dab tsi?
A: Nws yog siv los ua cov ntsia liaj qhov rooj rau steel- rau- steel load- cov kabmob sib txuas hauv cov txuas hniav, cov tsev, thiab cov khoom siv hlau.
Q: Qhov txawv ntawm ASTM A325 thiab ASTM A490 bolts yog dab tsi?
A: ASTM A325 yog siv rau kev sib txuas ntawm cov qauv hlau, thaum ASTM A490 muab lub zog tensile ntau dua rau qhov hnyav dua - lub luag haujlwm ntawm daim ntawv thov fastening.
Q: ASTM A325 bolts siv tau sab nraum zoov?
A: Yog. Rau qhov chaw sab nraum zoov lossis raug pom, kub -dip galvanized lossis Hom 3 weathering steel ASTM A325 bolts feem ntau yog siv rau kev tiv thaiv corrosion.
Q: Puas yog ASTM A325 bolts sib hloov nrog tus qauv hex bolts?
A: Tsis yog. ASTM A325 bolts yog cov ntaub ntawv pov thawj thiab yuav tsum tau siv tsuas yog thaum tsim qauv tsim qauv qhia cov qauv - qib yuav tsum tau ua.
Q: Cov txiv ntseej thiab cov ntxhua khaub ncaws dab tsi yuav tsum tau siv nrog ASTM A325 bolts?
A: Lawv yuav tsum tau siv nrog hnyav hex txiv ntseej thiab cov txheej txheem hardened washers los xyuas kom meej preload thiab load hloov nyob rau hauv steel kev twb kev txuas.
Q: Dab tsi kev lag luam feem ntau siv ASTM A325 bolts qauv?
A: Lawv tau siv dav hauv kev tsim kho steel, choj engineering, fais fab nroj tsuag, roj & roj cov qauv, thiab kev tsim khoom hnyav.
