How to Choose the Right Composite Deck Screws
Whether you’re a custom decking contractor or a long-time home addition pro, you already know that materials can make the difference between an ordinary deck and a show stopping backyard space. While your customer may only be thinking about composite deck board colors and grain, you know the right composite decking fasteners can play a starring role all their own.
Choosing screws for composite decking may seem like a simple task, but your choice of fastener may be one of the most significant decisions you make when building a deck. The size, composition and style of the composite decking fasteners you select can have a significant impact on how safe, durable, structurally stable and beautiful your next decking project is.
Why you need composite deck screws
While it is possible to use traditional wood deck screws when installing composite boards, it's best to use specialized composite screws. They feature better weather- and corrosion-resistance than ordinary wood screws. If you are installing boards with hidden fasteners, you have more options to choose from. Just make sure that the head size of your screw is large enough to secure the hidden fastener but not so wide that it prevents proper gapping between the boards.
When installing through the face of the deck board, however, screws made specifically for composite decks are the best choice. The typical large heads of wood deck screws can pop out when composite deck boards naturally contract. This may not only cause safety hazards, but it creates aesthetic issues for your clients as well. Other screws can also create an unsightly bulge of plastic around the head because plastic isn’t milled as effectively as wood for a clean, flush finish.
If you select specially engineered composite decking screws instead, you’ll experience the following benefits:
- Trim head and special shank designs that help prevent cracking or splitting
- Special threads to manage the plastic shavings from composite decking
- Countersinking for a clean, flush finish
- Superior weather and water resistance comparable to composite deck boards
