heavy hex boltHeavy hex bolts have a larger head than a standard hex bolt. They are used for bridges, highway, buildings and other construction projects. Heavy hex bolts work well with construction materials such as wood and steel. We also offer structural bolts, which differ from heavy hex bolts since they have shorter threads than heavy hex bolts.
