Simpson Strong-Tie. The Strong Drive SDWS screw is designed for structural wood-to-wood applications, including securing deck ledgers. The low-profile, 0.22-inch–diameter screw offers an alternative to traditional lag bolts and can manage higher loads than other lag solutions, the maker says. The fastener features a patented 4-cut tip to eliminate pre-drilling, and a unique thread design to boost holding power. Available in 3- to 10-inch lengths, the screw features a double-barrier coating to protect against corrosion. 800.999.5099. www.strongtie.com.
