WoodPro Composite Deck Screws are the perfect screw for your composite deck installation project. The secure STAR drive recess helps reduce bit stripping and a sharp Type-17 point allows for easy starting and effortless drilling. The dual thread design eliminates the mushrooming effect in composite and wood materials and provides a clean flush finish. These screws are color coated by PPG Industries with an Electro-Popliteal coating to match your deck. PPG Industries E-Coat is superior to other types of coating because it allows for a thinner coat while still maintaining over 1,000 hours of salt spray protection. The coating is extremely durable in all-weather applications and will not chip or rub off. PPG coating is rated for use in treated lumber. Package includes one STAR bit.
