Power Pro Structural Lag Screws, 5/16 In X 3 In, 40 Pieces, Corrosion Resistant

Power Pro Structural Lag Screws are heavy-duty fasteners engineered for construction, deck building, and woodworking projects where strength and durability matter. These 5/16-inch by 3-inch screws feature a corrosion-resistant epoxy coating designed to withstand outdoor exposure and treated lumber environments.

The unique design minimizes driving friction and torque, making installation easier and faster without the need for pre-drilling. The dome head includes an easy-to-read depth code for quality inspection after installation, and the star drive style ensures a snug, slip-free connection that resists cam-out.
