Bolts are often used when fastening items together for both structural and decorative purposes. Our 3/8" x 5 1/2" hex head bolts are available in bulk, providing a smooth and traditional aesthetic. For an industrial style, opt for a smooth texture, while hammered or pyramid textures offer a rustic feel. When purchasing, choose nuts and washers with the same diameter as the bolt for optimal performance. For structural purposes, a diameter of 3/8" or larger is recommended.
