Structural Bolts are a specialized heavy type of hex bolt intended for use in large structures, such as buildings and bridges. This bolt is designed to withstand the loads of steel-to-steel structural connections. They contain a flat, washer-faced bearing surface and a chamfered thread point. Galvanized plating protects the bolt from corrosion; typically used in outdoor applications.
