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.

Good screws. Drive well.

These were good screws. They drove into wet treated lumber without difficulty. The only issue for me was they have a unique driver configuration and I had to constantly switch out the drivers on my impact tool because my other screws were not compatible with this driver. Small price to pay for a strong and easy to use screw.

Reliable, Great bucket size!

We use these frequently at our shop and with the deeper thread spacing these drive far better than any other competitor that we have found. Highly reliable not prone to snapping or bending. Would recomend over any other brand.
