Strong-Drive® SDWH Structural Wood Screws - Large Hex-Washer Head - For Structural Wood-to-Wood Connections - Designed to provide an easy-to-install, high-strength alternative to through-bolting and traditional lag screws. Bold thread design provides superior holding power and cinches fastened members together for consistent installation. Patented 4CUT point ensures fast starts, reduced installation torque and eliminates the need for pre-drilling in most applications. Knurled shank section above the threads makes driving easier. Under-head nibs offer greater installer control when seating the head. Large head provides maximum bearing area. Double-barrier coating provides corrosion resistance equivalent to hot-dip galvanization, making it suitable for many exterior and preservative-treated wood applications. Large hex-washer head provides excellent bearing area for a secure connection. Hex drive reduces cam-outs for easier driving. Installs best with a low-speed 1/2" drill motor with a 5/16" hex driver (bit included in each package).
