Product Details
✓Professional Trailer Deck Installation Screws: Engineered specifically for demanding trailer flooring, featuring the sharp Type F Thread Cutting Structure. This allows the 5/16-18 x 2-1/2" Trailer Deck Screws Self Tapping to aggressively bite and cut into pressure-treated lumber and hardwoods for a fast, secure hold, ensuring your trailer deck remains solid and rattle-free
✓High-Torque T-40 Star Drive: Utilizes a T-40 Star (Torx) Drive design, delivering superior torque transfer efficiency compared to standard drives. This minimizes driver bit slippage and cam-out, reduces wear on your tools, and allows for powerful, fast installation even during high-volume trailer decking projects
✓Durable Black Phosphate Anti-Corrosion Finish: The screws are treated with a protective Black Phosphate Coating. This significantly enhances resistance to rust and corrosion caused by exposure to road salt, moisture, and outdoor elements, extending the service life of your trailer deck screws in harsh environments
✓Self-Tapping Design for Efficiency: The advanced Self Tapping tip combined with the Type F Thread eliminates the constant need for pre-drilling pilot holes in most trailer deck woods. This saves significant time and effort during installation, streamlining the deck replacement or repair process while reducing the risk of wood splitting
✓Optimized Specifications & Bulk Value: Features the ideal 5/16-18 x 2-1/2" size for robust trailer decking applications, providing excellent penetration depth and holding power. Each bulk package contains 100 ready-to-use screws, offering exceptional value and convenience for both larger trailer projects and smaller repairs
