Zimapangidwa ndi ma bolts osunthika, machubu okulitsa, zochapira zosalala, zochapira masika ndi mtedza wa hexagonal. zinthu zambiri mpweya zitsulo (monga Q235), ndi makulidwe a wosanjikiza electrogalvanized ndi 5-12μm, amene akukumana ISO 1461 kapena GB/T 13912-2002 mfundo.

Rainbow chromate passivation (c2C) amachitidwa pamaziko a electrogalvanizing kupanga mtundu passivation filimu ndi makulidwe pafupifupi 8-15μm. Mayeso opopera mchere amatha kupitilira maola 72 popanda dzimbiri loyera.

Wopangidwa ndi Q235 carbon steel ndi zipangizo zina, pamwamba ndi electro-galvanized, ndipo makulidwe ❖ kuyanika nthawi zambiri 5-12μm, amene amakwaniritsa zofunika pambuyo mankhwala c1B (buluu-woyera zinki) kapena c1A (wowala nthaka) mu GB/T 13911-92 muyezo.

Maboti a Stud ali ndi ulusi kumapeto onse awiri ndi ndodo yopanda kanthu pakati, yomwe imagwiritsidwa ntchito kulumikiza mbale zakuda kapena kulowa mkati (muyezo wa GB/T 901). Zida wamba ndi 45 # zitsulo kapena 40Cr, zokhala ndi malata kapena zida zakuda.

Mutu wa hexagon socket bolt uli ndi dzenje la hexagon ndipo uyenera kulumikizidwa ndi wrench socket socket wrench (standard GB/T 70.1). Zida zodziwika bwino ndi 35CrMo kapena 42CrMo, ndipo chithandizo chapamwamba chimagawidwa m'magulu atatu: electrogalvanized, color zinc-plated, ndi black zinc-plated.

Mutu wa bolt wa ngolo ndi semicircle yayikulu, ndipo khosi ndi lalikulu kuti mupewe kuzungulira (muyezo wa GB / T 14). Zida wamba ndi Q235 kapena chitsulo chosapanga dzimbiri, chokhala ndi malata kapena chakuda pamwamba.

Maboti a hexagonal ndi ma bawuti odziwika kwambiri okhala ndi mitu ya hexagonal ndipo amagwiritsidwa ntchito ndi mtedza (standard GB/T 5780). Zida wamba ndi Q235 kapena 35CrMo, zokhala ndi malata kapena zakuda.
