GRK RSS Rugged 1/4 In. x 1-1/2 In. Star Drive Washer-Head Structure Screw (50-Count)

GRK RSS Rugged Structural Screw is a structural fastener designed for ease of installation and the strongest of connections.

With proprietary features like the Zip-Tip, and W-Cut thread, RSS fasteners drive into most woods without the need for pre-drilling.

The specially engineered design results in a low-effort installation, especially compared to conventional lag screws.

RSS Rugged Structural Screws have a Climatek Coating for installation in both interior and exterior conditions where exposure to moisture is intermittent and is code-approved for use in treated lumber.
