Hex Bolt Din 931 / iso4014 933 / iso4017 Qib 8.8
Qib 8.8 siab tensile steel feem ntau hu ua cov qauv qib rau bolts.Nws yog cov ntaub ntawv ntau tshaj plaws ntawm cov khoom siv tensile siab thiab feem ntau yog stocked nyob rau hauv cov tiav tiav los yog zinc.
HEX BOLT DIN 931/ISO4014 933/ISO4017 QIB 8.8 yog cov khoom siv zoo tshaj plaws tsim los muab kev ruaj ntseg thiab ruaj khov rau kev siv hnyav.Qhov no hex ntsia liaj qhov rooj yog tsim los nruj DIN thiab ISO cov qauv, kom ntseeg tau zoo ib yam thiab kev ntseeg tau.
Nrog rau qib 8.8 kev ntsuas, lub ntsia liaj qhov rooj no tuaj yeem tiv taus qhov hnyav thiab nruj, ua rau nws zoo tagnrho rau siv ntau yam kev lag luam thiab kev tsim kho.Nws cov duab hexagonal ua kom muaj kev ruaj ntseg tuav, thaum nws lub ntsej muag du tiav muaj kev tiv thaiv corrosion zoo heev, pab tswj kev ua haujlwm ntev.
Txawm hais tias koj tab tom nrhiav kom ruaj ntseg cov tshuab hnyav lossis tsim cov txheej txheem muaj zog, HEX BOLT DIN 931 / ISO4014 933 / ISO4017 GRADE 8.8 yog qhov kev xaiv zoo tshaj plaws rau koj cov kev xav tau fastening.Cia siab rau nws qhov zoo tshaj plaws, lub zog, thiab kav ntev kom koj cov haujlwm ruaj ntseg thiab vam khom.
