GRK Fasteners RSS structural wood screws are engineered fasteners designed for superior holding power and ease of installation in wood framing, decking, cabinetry and furniture assembly. The combination of a washer head for enhanced clamping, a star drive that resists cam-out, and a fast-bite tip for efficient starts makes these screws a premium choice for both professional contractors and serious DIYers tackling demanding projects.
The W-Cut thread design and innovative tip geometry work together to drive smoothly into wood with minimal effort, often eliminating the need for pre-drilling on many projects and saving significant time on the job site. These black-coated screws are approved for use in treated lumber and deliver the reliable performance needed for structural applications.
