Hot dip galvanized nuts are fasteners with a surface treated with hot-dip galvanizing, which have excellent rust and corrosion resistance and are suitable for mechanical and building applications in outdoor or humid environments. The hot-dip galvanizing process forms a layer of zinc iron alloy on the surface of the nut, providing long-term protection against rust and corrosion. This type of nut is commonly used in applications such as steel structures, bridges, power towers, guardrails, etc. that require long-term exposure to harsh environments. The characteristics of hot-dip galvanized nuts are strong durability, easy installation, low maintenance costs, and the ability to withstand large mechanical stresses. When choosing hot-dip galvanized nuts, attention should be paid to their size, thread specifications, and material grade to ensure compatibility with bolts or other fasteners.
