Starborn Deckfast No. 9 S X 1-7/8 in. L Star Pan Head Fascia Screws 100. Pack of 4. The fascia system is designed to accommodate the large amount of expansion and contraction that can occur with many composite deck fascia boards. The pre-drilling tool creates an over-sized hole for the fascia screw, so that the fascia board hangs from the screw and can expand and contract without putting a large amount of force on the fastener.
