Description
Simpson Strong-Tie SDWS Exterior Timber Screws are engineered for serious strength in outdoor wood projects. From framing a new deck to building a retaining wall, these screws deliver lasting hold and corrosion resistance—without slowing you down.
They feature a sharp, fast-start point that eliminates the need to pre-drill, while the bold thread design locks into wood for a secure grip. A large washer-style head increases pull-through resistance and applies even clamping pressure across joints.
Protected with a Double-Barrier Coating, these screws are made to perform in tough weather and pressure-treated lumber, giving DIYers and pros alike a reliable fastener that’s built to last.
Key Features:
- Double-Barrier Coating – Resists corrosion in wet, outdoor conditions and works with pressure-treated wood.
- Fast Start Point – No pre-drilling needed; drives quickly and smoothly into wood to save time.
- Large Washer Head – Distributes force for stronger joints and prevents the screw from sinking too deep.
- Aggressive Threading – Bites into wood for a tight, reliable hold—even in dense or treated lumber.
