Simpson Strong-Tie Strong-Drive No. 5 Sizes X 5 In. L Star Low Profile Head Bold Structural Screws

The Simpson Strong-Tie Strong-Drive SDWS22500DB-R50 is a high-strength structural timber screw engineered as an easy-to-install alternative to through-bolting and traditional lag screws. These 5-inch screws are ideal for wood-to-wood connections in structural applications, including ledgers, deck framing, and home construction projects. The screws deliver reliable holding power under load without requiring pre-drilling in most applications, making them suitable for both professional contractors and DIY enthusiasts.

Built with a patented sawtooth point and deep 6-Lobe (Torx) star drive, these screws ensure fast starts and reduced installation torque while minimizing cam-out during driving. The low-profile washer head design sits flush to the surface with underhead nibs that reduce splintering, providing both a clean appearance and structural integrity. A double-barrier coating makes these screws suitable for exterior and preservative-treated wood applications, ensuring durability in demanding environments.
