Hex Bolts are made of low carbon steel, these fasteners are applicable for most low strength commercial and industrial uses. Galvanized plating protects the bolt from corrosion HDG hex bolts are used in a wide range of applications due to their durability and corrosion resistance. Here are some common uses: Construction: HDG hex bolts are used in construction for heavy machinery, steel structures, and bridges, providing stable and reliable connections under various climatic conditions. Marine and Coastal Applications: They are suitable for marine environments, meeting IAPMO-UES ER-192 code requirements for common wood framing applications. Transportation: HDG hex bolts are used in ships, vehicles, mining machinery, and aircraft, ensuring the firmness and durability of connections in harsh environments. Electrical and Mechanical Manufacturing: They are used in high-voltage lines, substations, generators, compressors, and machinery, providing high strength and stability. HDG hex bolts are a reliable choice for projects that require considerable gripping strength and are exposed to moisture, chemicals, or extreme temperatures. They are essential for ensuring the integrity and longevity of structures and equipment in various industries.
