Bulk Composite Deck Screws
Bulk composite deck screws are engineered specifically for composite and PVC decking boards. Their thread designs and head styles eliminate mushrooming, reduce surface bulging, and ensure a clean, flush finish. Perfect for contractors or DIYers tackling larger projects where loose, bulk packaging saves time and cost.
Why Choose Bulk Composite Screws?
Unlike standard wood screws, composite deck screws are tailored to the unique density and composition of composite boards. Buying in bulk means you’ll always have plenty on hand for big projects without running short mid-install.

Composite Deck Screw FAQs
Can I use regular wood screws in composite decking?
No. Composite deck screws are designed with special threads and heads to prevent mushrooming and surface damage. Wood screws can cause unsightly bulges.
Do I need stainless steel composite screws?
For coastal, poolside, or high-moisture environments, stainless steel is the best option for preventing rust and staining. Coated steel is sufficient for most inland projects.
What size screw should I use for composite decking?
For standard 1” composite boards, 2 ½” screws are most common. Thicker boards may require longer screws for proper fastening.
