FAQ
Dab tsi yog cov khoom siv zoo tshaj plaws rau hex bolts hauv kev tsim kho sab nraum zoov?
Stainless hlau yog qhov kev xaiv zoo tshaj plaws rau kev tsim kho sab nraum zoov. Nws cov corrosion kuj ua kom durability nyob rau hauv cov av ntub los yog ntub dej. Rau cov nqi-rhiab heev, carbon steel nrog tiv thaiv txheej zoo li galvanization tuaj yeem ua tau zoo.
Cov kws tshaj lij yuav ua li cas thiaj li ua tau zoo bolt thiab txiv ntseej compatibility?
Cov kws tshaj lij yuav tsum sib phim cov ntaub ntawv, xov suab, thiab qhov loj me. Siv cov cuab yeej xws li calipers thiab xov ntsuas ntsuas kom ntsuas qhov tseeb. Kev sab laj cov lus pom zoo ntawm cov chaw tsim khoom kuj tseem pab kom tsis txhob muaj qhov tsis sib xws.
Vim li cas cov coatings tseem ceeb rau hex bolts thiab ceev?
Coatings tiv thaiv fasteners los ntawm corrosion, ncua lawv lifespan. Zinc plating, galvanization, thiab phosphate coatings muab kev tiv thaiv sib txawv. Qhov kev xaiv nyob ntawm ib puag ncig raug thiab cov kev xav tau ntawm daim ntawv thov.
Yuav tsum tau kuaj xyuas cov fasteners ntau npaum li cas?
Fasteners yuav tsum tau soj ntsuam tsis tu ncua, tshwj xeeb tshaj yog nyob rau hauv high-stress los yog corrosive ib puag ncig. Txhua hli kuaj xyuas cov cim ntawm hnav, corrosion, los yog xoob pab tswj cov cuab yeej kev nyab xeeb thiab kev ua haujlwm.
Puas muaj zog fasteners tsim nyog rau txhua daim ntawv thov kev tsim kho?
High-strength fasteners yog qhov tseem ceeb rau cov khoom hnyav lossis cov xwm txheej hnyav, xws li kev sib txuas steel hlau lossis cov tshuab hnyav. Rau cov ntawv siv sib dua, cov txheej txheem-qib fasteners yuav txaus, yog tias lawv ua tau raws li qhov yuav tsum tau ua.
