Description

Simpson Strong-Tie SDWS Timber Screws (Exterior Grade) are your go-to fasteners when strength and weather resistance matter. Ideal for outdoor framing, landscaping, or heavy-duty builds, these structural wood screws help DIYers get pro-level results without the need for pre-drilling.

Coated with a high-performance Double-Barrier finish, they resist corrosion from rain, moisture, and treated lumber. The large washer head adds serious clamping power, while the aggressive thread design ensures a fast bite and tight hold in even the toughest wood.

Whether you’re building a retaining wall, deck frame, or outdoor stair set, these screws are engineered to perform in real-world outdoor conditions.

Key Features:

  • Double-Barrier Coating – Engineered for high corrosion resistance in outdoor environments and pressure-treated wood.
  • No Pre-Drilling Required – Save time and effort on large builds with a fast-start point that drives clean and deep.
  • Large Washer Head – Delivers high clamping force and helps prevent pull-through in structural applications.
  • Aggressive Thread Design – Cuts quickly into lumber, offering a secure hold even in dense or treated wood.
