Hot-Dip Galvanized A325 Heavy Hex Bolts

The Hot-Dip Galvanized A325 Heavy Hex Bolt is a high-strength structural bolt that conforms to the ASTM A325 standard. These bolts are widely used in steel structure connections in buildings and bridges. The hot-dip galvanizing process ensures superior corrosion resistance, making them suitable for long-term use in outdoor or harsh environments. The heavy hex head design provides maximum strength to withstand high tensile and shear forces, making it ideal for structural connections requiring high-strength fastening solutions.
