- [High-Strength & Durable Performance]Our 5/16-18 x 3" trailer deck screws feature a thread-cutting (Type 7) design that resists torque, shear, and tension, ensuring a secure hold under heavy loads. Made from hardened steel with black phosphate coating, they resist rust and corrosion for long-lasting use in trailers, flooring, and outdoor projects.
- [Self-Tapping & Easy Installation]The blunt tapered point and multi-cutting edges allow these screws to drill smoothly into hardwoods and softwoods, saving time and effort. Ideal for trailer decking, flooring panels, and DIY projects requiring strong, split-free fastening.
- [T30 Torx Drive for Maximum Torque]The star drive (T30) design prevents cam-out and stripping, enabling higher torque transfer for faster, more efficient installation. Perfect for high-intensity use by professionals and DIYers alike.
- [Upgrade Reinforcing Ribs & Included Drill Bit]Increase torsional strength and prevent bit slippage.The flat countersunk head sits flush with the surface for a clean, professional look, while the included drill bit ensures precise pre-drilling when needed.
