SPAX Hex Washer Powerlags - The Ultimate Structural Fastener: Delivers unmatched strength, speed, and efficiency for wood-to-wood structural connections. Designed for high-torque applications and features a hex head with a built-in washer for maximum pull-down force, eliminating the need for separate washers. With thread serrations, Powerlags require up to 40% less driving torque, making installation faster and easier while helping to prevent wood splitting.
Perfect for framing, timber construction, log home building, and heavy-duty interior projects, these structural fasteners are IRC/IBC code compliant and stamped for easy length identification. No pre-drilling required for 1/4" and 5/16" sizes, while lead holes are recommended for larger diameters.
