Simpson Strong-Tie Strong-Drive SDWS Structural Timber Screws

Approx read time: 1 minute

The SDWS is the 2nd Generation, redesigned with a patented SawTooth™ point. It delivers faster starts, less torque, and eliminates the need for pre-drilling. All this reduces tool wear and extends your battery life!

No pre-drilling means more screws installed and less labour for you compared to conventional installation. The SDWS is the advanced alternative to bolting timber, or batten and coach screws, being 30% faster and 10% stronger than an equivalent batten screw.
