Deck Screw vs. Wood Screw
Both drive into wood, but deck screws are coated and threaded for outdoor work.
| Feature | Deck Screw | Wood Screw |
|---|---|---|
| Coating | Corrosion-rated for outdoors | Plain steel or light coating |
| Thread | Deep and aggressive, often twin-start | Standard tapered thread |
| Head | Bugle or flat with nibs | Flat, oval, or round |
| Drive | Usually star or Torx | Phillips or slotted |
| Best for | Decks, fencing, outdoor framing | Interior woodwork |
Verdict
Deck screws are the outdoor, corrosion-rated upgrade of the wood screw. Indoors, a plain wood screw is fine and cheaper.
