If using a hammer drill, be sure to switch from hammer-drill mode to drill-only mode for this step. Fasten the cleat to the brick with 2 ½-inch concrete screws. Attach the side cleats in the same manner. Drive the screws through the pilot holes you previously drilled in Step 4.

Note: If you're attaching the mantel to a conventional wood-stud wall, use 3-inch decking screws instead of concrete screws.
