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. Plain finish, or bare metal, may or may not have a coating of light oil to resist corrosion.
