Simpson Strong-Tie has expanded its line of stainless steel deck screws. Deck-Drive DWP screws with both trim and flat heads are available in more sizes and lengths, making them suitable for most exterior, wood-to-wood applications. The screws come in both Type 305 and Type 316 stainless. Their thread design reduces driving torque by 35% when compared with other fasteners on the market, according to the manufacturer, so builders should be able to drive more screws on a single battery charge. Trim heads come in lengths from 1-inch #7 to 4-inch #9; flat heads range from 1 1⁄4-inch #8 to 5-inch #12. Simpson Strong-Tie, strongtie.com
