Spax PowerLags are premium structural screws engineered for demanding wood-to-wood fastening applications. The 1/4 inch by 6 inch size with T-30 Torx drive and washer head design makes these screws ideal for framing, decking, outdoor furniture, and other structural projects where reliability and corrosion resistance matter. Whether you’re a professional contractor or a dedicated DIYer, these fasteners deliver the performance and durability your projects demand.
The innovative design of PowerLags eliminates common fastening challenges. The patented thread serrations reduce driving torque by up to 40% and allow you to skip pre-drilling in many applications, speeding up installation significantly. The washer head provides a larger bearing surface that grips securely and resists pull-through, while the HCR (High Corrosion Resistance) coating protects against rust and weathering—especially important for treated lumber and challenging environments. Each screw is stamped with its length for easy on-site identification.
