0.220"x4" Strong-Drive® SDWS T40 Timber Screw (12/BX)

The Strong-Drive SDWS Timber screw is designed to provide an easy-to-install, high-strength alternative to through-bolting and traditional lag screws.

• Underhead nibs allow for head to drive flush to surface with reduced splintering.
• Large washer head provides a large bearing area.
• Size identification on all SDWS screw heads.
• 6-lobe T40 drive provides positive engagement that makes the screw easy to drive and improves bit life.
• Double-barrier coating provides corrosion resistance equivalent to hot-dip galvanization, making it suitable for certain exterior and preservative-treated wood applications.
