The two-part Fascia-Fastening Solution is designed specifically for the installation of increasingly popular composite and PVC fascia boards, to address expansion and contraction issues that can lead to material failure due to environmental exposure. First, the fascia counterbore bit is used to counterbore a hole through the board that’s wider than the screw shank. Then the fascia screw is driven through this hole and into the backing substrate. The wider hole allows room for expansion and allows the screw head to sit flush with the board.
