Grade 8.8 M8*100 Alloy Steel Hot Dip Galvanized External Hexagon Bolts

Grade 8.8 M8*100 Alloy Steel Hot-Dip Galvanized External Hexagon Bolts are engineered for use in outdoor structures, construction steel frames, bridges, and any application where long-term corrosion resistance is as important as mechanical performance. Hot-dip galvanizing (HDG) deposits a thick, metallurgically bonded zinc layer — far more durable than electro-galvanizing — making these bolts suitable for coastal, tropical, or high-humidity industrial environments.
