Overview

The GRK Fasteners RSS™ Rugged Structural Screw, item 12127-GRK (specifically a #10 x 1-1/2" size, often found in Handy-Paks of 50 count), is a premium, code-approved fastener designed for high-strength structural applications in wood. Made of specially hardened steel, this screw provides exceptional tensile, torque, and shear strength, making it a highly efficient and often superior alternative to traditional lag screws.

Featuring GRK's signature innovations like the Zip-Tip™ for instant bite without pre-drilling, and W-Cut™ threads for reduced driving torque, the RSS™ screw ensures fast and easy installation. Its unique design also incorporates a round washer head with a built-in shield and an added shoulder, allowing for precise centering in pre-drilled hardware and eliminating sharp edges. The Climatek™ coating provides AC257 code-approved corrosion resistance for use in treated lumber, making it suitable for both interior and exterior applications.
