Easy to drive and engineered for superior holding power, the Strong-Drive® SDWS Timber screw from Simpson Strong-Tie provides contractors and do-it-yourselfers alike with an easy-to-install, high-strength alternative to through-bolting and using lag screws across many common wood framing applications.
Featuring a SawTooth™ point for fast starts and reduced installation torque, your customers will appreciate the SDWS Timber screw’s bold thread design for superior holding power and its underhead nibs for greater control when seating the screw head. A large, low-profile washer head provides maximum bearing area, along with easy-to-read size identification.
The 6-lobe T40 drive enables positive engagement and easy driving to improve bit life and reduce operator fatigue, and a double-barrier coating delivers corrosion resistance equivalent to hot-dip galvanization, making the SDWS Timber screw suitable for a variety of exterior and preservative-treated wood applications. The SDWS Timber screw also is available in Type 316 stainless steel when strength and severe corrosion resistance are critical.
