Strong-Drive® SDWS TIMBER Screw (Interior Grade) Installation
Strong-Drive® SDWS TIMBER Screw (Interior Grade) Installation

The Strong-Drive SDWS Timber screw from Simpson Strong-Tie is a faster, easier, stronger fastening solution for structural wood-to-wood connections. The SDWS screw’s patented SawTooth point, combined with its coarse thread pattern and mid-shank knurls, reduces torque and makes driving easy. Unlike traditional lag screws, the SDWS screw requires no pre-drilling — saving your customers time and labor costs. A large, heavy-duty shank offers high strength and durability, and it’s deep, 6-lobe, T40 recess ensures positive engagement for a secure drive. The low-profile head provides a broad load-bearing area that eliminates the need for washers and creates a flush, unobstructed surface. The SDWS Timber screw comes in a range of sizes to suit a wide variety of applications, and features a corrosion-resistant coating ideal for exterior and preservative-treated wood applications.
