Specifications
Simpson Strong-Tie Outdoor Accents® Structural Wood Screws give you the best of both worlds; rugged strength and a decorative finish. Designed for outdoor wood framing and accent projects, these screws deliver reliable hold while complementing black hardware in the Outdoor Accents line.
The large hex-head design provides powerful driving torque and a clean, finished look when paired with Outdoor Accents hex-head washers (sold separately).
Each screw is finished with a black corrosion-resistant coating that blends beautifully with decorative hardware. Whether you're building a pergola, pavilion, or custom outdoor structure, these screws offer the strength you need with the style you want.
Key Features:
- Decorative Black Finish – Complements Outdoor Accents® hardware for a clean, professional appearance.
- Corrosion-Resistant Coating – Protects against the elements, making it suitable for treated wood and outdoor exposure.
- No Pre-Drilling Needed – Patented tip drives easily into wood, saving time on installs.
- Hex Head Design – Pairs with Outdoor Accents® hex-head washers to replicate the look of bolted connections.
