Powerlag 1/4 In. In. X 4 In. L T-30 Washer Head Serrated Structural Screws

Spax PowerLags are heavy-duty structural screws engineered for demanding wood-to-wood applications. Featuring a T-30 drive and washer head design, these screws deliver reliable fastening performance for framing, decking, furniture assembly, and outdoor projects where strength and corrosion resistance matter.

The patented thread serrations eliminate the need for pre-drilling, allowing you to work faster while reducing driving torque by up to 40%. The HCR (High Corrosion Resistant) exterior coating protects against rust in treated lumber and coastal environments, ensuring your projects withstand the elements. Each screw is stamped with its length for quick on-site verification and material identification.
