Decorative Hardware for Outdoor Projects: Strength You Can See
Simpson Strong-Tie’s Outdoor Accents line of decorative hardware delivers structural strength and architectural style in one package. Designed specifically for outdoor projects like pergolas, decks, gazebos, and pavilions, these fasteners and accessories complete the look and performance of your framing connections.
Each piece is crafted for durability, load-rated performance, and a clean black powder-coated finish that pairs perfectly with the full line of Simpson Outdoor Accents decorative connectors.
What Is Decorative Hardware?
Decorative hardware refers to the structural fasteners and accessories that are designed not only for strength, but for visual appeal. In Simpson’s Outdoor Accents series, that means black-finished screws, hex-head washers, bolts, and nuts that complement every connector, bracket, and strap in the system.
This collection includes:
- SDWS structural screws with black double-barrier coating
- Hex-head washers for a decorative bolt appearance
- Outdoor-rated nuts, bolts, and fastener packs
Every item is engineered for compatibility, ensuring your build stays strong and looks professional from top to bottom.
Black Fasteners with Built-In Protection
Simpson’s decorative hardware is more than just good-looking. These components are manufactured with high-grade carbon steel and finished with a corrosion-resistant black coating, suitable for use with pressure-treated lumber and long-term outdoor exposure. The SDWS screws in particular feature a double-barrier coating system tested to ASTM standards for corrosion performance.
Match Your Hardware to Your Connectors
Using mismatched fasteners can compromise both the strength and style of your build. That’s why Simpson’s decorative hardware is color-matched and performance-matched to every Outdoor Accent connector, from post bases and joist hangers to gable plates and angle brackets.
Each fastener blends in with your structural connectors, keeping the focus on clean lines and craftsmanship, not mismatched screws or exposed hardware.
Common Applications
- Pergolas and pavilion frames
- Deck railing and framing connections
- Outdoor kitchens and bar structures
- Fences, arbors, and garden trellises
- Heavy-duty patio covers and rooflines
Installation Tips
Simpson’s decorative screws install easily with standard drills and do not require pre-drilling in most wood types. The hex-head washers are designed to slide over the screw head to simulate the appearance of a bolted connection, offering the look of a carriage bolt with the speed of a screw install.
Use only Simpson-approved fasteners for Simpson connectors to maintain code compliance and structural ratings.
