Bolts are typically used for fastening items together. Both used for structural and decorative applications. Our square bolts appeal more to a rustic design especially with our texture of hammered or pyramid. These square head bolts add just the flare you need for your project. When purchasing nuts and washers with this item you will want to select the same size as the diameter of the bolt.
We recommend using 3/8" diameter and above for structural applications.
