Hex Bolt Din 931 / iso4014 933 / iso4017 Gulu 8.8
Grade 8.8 high tensile zitsulo nthawi zambiri zimatchedwa structural grade for bolts. Ndiwo mtundu wodziwika bwino wazinthu zolimba kwambiri ndipo nthawi zambiri zimakhala zomaliza kapena zinc.
HEX BOLT DIN 931/ISO4014 933/ISO4017 GRADE 8.8 ndi chomangira chapamwamba kwambiri chopangidwa kuti chipereke kukhazikika kotetezeka komanso kolimba kwa ntchito zolemetsa. Bawuti iyi ya hex imapangidwa motsatira miyezo yolimba ya DIN ndi ISO, kuwonetsetsa kuti imagwira bwino ntchito komanso yodalirika.
Ndi mlingo wa giredi 8.8, bawuti iyi imatha kupirira kupsinjika ndi kupsinjika kwakukulu, ndikupangitsa kuti ikhale yabwino kugwiritsidwa ntchito m'mafakitale osiyanasiyana ndi zomangamanga. Maonekedwe ake a hexagonal amaonetsetsa kuti akugwira motetezeka, pamene mapeto ake osalala amapereka kukana kwa dzimbiri, zomwe zimathandiza kuti zisamagwire ntchito kwa nthawi yaitali.
Kaya mukuyang'ana kuteteza makina olemera kapena kumanga zolimba, HEX BOLT DIN 931/ISO4014 933/ISO4017 GRADE 8.8 ndiye chisankho chabwino kwambiri pazosowa zanu. Khulupirirani zabwino zake, mphamvu zake, ndi kulimba kwake kuti mapulojekiti anu akhale otetezeka komanso odalirika.
