Powerlag 5/16 In. In. X 6 In. L T-40 Washer Head Serrated Structural Screws

Spax PowerLags are premium structural screws engineered for demanding wood-to-wood fastening applications. The washer head design provides a larger bearing surface, creating secure and stable connections in construction projects, decks, ledgers, and outdoor structures. These screws are built to handle the demands of both professional contractors and serious DIY builders who require reliable fastening solutions for exterior and interior construction work.

The patented serrated threads cut directly into wood without requiring pre-drilling, reducing installation time and driving torque requirements by up to 40%. With high corrosion resistance (HCR) coating, these screws offer superior protection against corrosion, making them ideal for use in treated lumber and coastal environments. The T-Star drive system minimizes cam-out for smoother, more efficient driving, while the length stamp on each head enables quick on-site identification without measuring.
