Cap Head Composite Deck Screws
Cap head composite deck screws are designed specifically for composite decking materials. Their unique head design prevents mushrooming and leaves a clean, finished appearance on the deck surface. With threads tailored for composite boards, they deliver long-lasting holds without damaging the material.
Why Choose Cap Head Screws?
Standard wood screws can cause bulging or splitting in composite boards. Cap head screws solve this by using a wider, specialized head and thread profile that ensures a flush, smooth finish while maintaining strength in dense composite materials.
Features
- Cap-Style Head: Minimizes mushrooming and surface distortion in composite decking.
- Flush Finish: Designed to sit cleanly in the deck surface for a polished look.
- Corrosion-Resistant Coatings: Protects screws from rust and staining over time.
- Composite-Specific Threads: Grip tightly to prevent loosening in synthetic boards.
