SPAX Powerlags Structural Screws: The ultimate heavy-duty fastener for heavy-duty wood-to-wood connections—no pre-drilling required. Engineered to replace conventional lags, serrated threads near the tip create a fast start, reducing driving torque by up to 40% compared to conventional lag screws. Designed for maximum holding power, these screws meet or exceed strict building and structural codes, making them the ultimate choice for heavy duty load-bearing applications and projects.

No Pre-Drilling Required – Spend less time on prep work, and more time getting the job done.
Superior Grip and Holding Power: Code Compliant IRC / IBC certified (DrJ TER No 1912-07) for deck ledger and multi-ply connections.
High Corrosion Resistance (HCR) coating ensures long-lasting durability in harsh outdoor environments.
Built-On Washer Head: Eliminate separate washers and streamline installation.
Each pack contains 150 pieces of 6" inch screws along with 1 high-quality T40 T-Star bits.
Convenient Length Stamping: Quick identification for accurate on-site use.
Thread Serrations: Up to 40% less driving torque, reducing material splitting.
SPAX Powerlags are the ideal replacement for conventional lags!
Great for patio, deck, treated lumber, and heavy duty outdoor projects.
