The GRK RSS Rugged Structural Screw is the premier alternative to traditional lag bolts, designed to provide high-tensile, torque, and shear strength for heavy-duty structural applications. Engineered with a patented design that eliminates the need for pre-drilling, these screws facilitate faster installations without the risk of wood splitting. The built-in washer head provides exceptional clamping force, while the Climatek coating ensures long-lasting corrosion resistance, making them ideal for both interior and exterior projects, including pressure-treated lumber.
Performance Features
- Climatek Coating: AC257 code-approved for use in treated lumber, providing superior corrosion protection.
- Zip-Tip: Features a sharp point and threads that bite instantly for fast penetration without pre-drilling.
- W-Cut: Lowers installation torque, allowing for smoother driving and reduced friction on the screw shank.
- CEE Thread: Enlarges the screw hole for the non-threaded portion, increasing drawing strength and reducing the likelihood of splitting.
- Star Drive Recess: Provides six points of contact to eliminate stripping and ensure a zero-wobble fit.
- Integrated Washer Head: Large head surface area offers maximum clamping force and prevents pull-through.
