Product overview
GRK RSS Black Structural Screw is a structural fastener designed for ease of installation and the strongest of connections while providing a bold finish. 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.
- Black coating matches decorative hardware for a cohesive looking deck build
- Fast-biting Zip-Tip eliminates pre-drilling and provides a fast start making it easy to get the strongest of connections
- Star drive recess has 6 points of contact, eliminating stripping
- Unique thread design draws two substrates together while its washer head allows zero gap joints
- Designed for outdoor and decking applications
- W-Cut: Low torque, faster drive
- Speedy lag bolt alternative with immense drawing power
- Climatek coating is AC257 Code approved for use in treated lumber
- Limited lifetime warranty
