GRK RSS (Rugged Structural Screw) Structural Screws are designed for strong, secure wood-to-wood connections in structural construction applications. The 6" length provides extended reach for fastening thicker lumber and joining substantial wood components. Ideal for securing beams, posts, framing members, and other structural wood assemblies, these screws are well suited for deck construction, timber framing, and general building projects. GRK RSS screws offer a practical alternative to traditional lag screws in compatible applications. Follow the manufacturer's installation instructions for proper fastening and performance.
