Heavy-Duty & Superior Rust Resistance for Outdoor Use: Engineered for permanent outdoor structures, these #14 x 4-1/2 inch deck screws boast a 4-layer epoxy coating that resists corrosion, humidity, and salt spray.

2. Star Drive (Torx) Head for Effortless, Fast Installation: The Torx (star) drive head provides maximum torque transfer, drastically reducing frustrating cam-out and bit slippage compared to standard Phillips heads.
