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.

Cap Head Composite Screw FAQs

Do I need cap head screws for composite decking?

Yes. Cap head screws are designed to reduce mushrooming and bulging, common issues when using standard wood screws in composite boards.

Can cap head screws be used with pressure-treated lumber?

They’re optimized for composite boards, but many can also be used in treated framing. For best results, use them specifically in composite decking surfaces.

Are stainless steel options available?

Yes. For maximum corrosion resistance, especially in coastal or poolside applications, stainless steel cap head screws are recommended.
