Best Deck Screws & Fasteners for DIYers
The right deck screws hold boards down for decades without rusting, popping, or splitting the wood. Coated structural screws beat old-style deck screws, and hidden systems give a clean, fastener-free surface.
What to look for
- ·Use coated or stainless screws rated for treated lumber. Cheap screws corrode and stain the wood.
- ·Self-countersinking heads (like GRK) sink clean without splitting, even in hardwoods. A star (Torx) drive resists stripping.
- ·For a clean surface, hidden-fastener systems (edge clips or plug systems) hide every screw.

Frequently asked
What screws should I use for a deck?+
Use exterior-rated coated, stainless, or specifically treated-lumber-compatible screws. Structural wood screws like GRK, Spax, and Simpson hold better than old-style deck screws, with star drives that resist stripping and heads that countersink cleanly.
Screws or hidden fasteners?+
Face-screwing is strongest and cheapest, with visible heads. Hidden fastener systems, edge clips or plug systems like CAMO, Starborn Pro Plug, or Cortex, give a clean fastener-free surface for more money and labor. Composite decks often use a hidden system.
What size deck screw do I need?+
For attaching 5/4 or 2x decking to joists, 2-1/2 to 3 inch screws are standard. Structural connections (ledgers, posts) use longer structural screws or lags rated for the load. Match length to roughly 2 to 2-1/2 times the board thickness.
Will deck screws rust?+
Cheap screws will, and they react with treated lumber to corrode faster and stain the wood. Use coated (like ClimaTek), hot-dipped galvanized, or stainless fasteners rated for treated wood, and stainless near saltwater.
Do I need to pre-drill?+
Quality self-countersinking screws usually do not require pre-drilling in softwood. Near board ends, in hardwoods, or with dense composite, pre-drilling prevents splitting and gives a cleaner result.
