Deck Plus Rustic Hardware Textured Flat-head Carriage Bolts are designed to fasten a wooden face to either a wood or metal frame. The textured head is made to resemble hand-forged metal and offers a low profile that can be recessed flush with the wood. The black epoxy coating offers superior resistance to rust and corrosion and creates a nice matte black decorative finish, which is essential for any antique, old world, or rustic interior design.
