GRK Structural Screws - Round Head RSS, #10 x 3 1/8" (50 pcs)

GRK RSS screw is made of hardened steel, providing exceptional tensile, torque and shear strength. Its sharp threads and points penetrate material quickly, including hardwood, while minimizing the risk of splitting thanks to thinner shanks.

• Engineered from hardened steel for high tensile, torque and shear strength.
• Sharp threads and points allow instant penetration, reducing splitting with smaller rods.
• Round head with integrated shield (washer type) without sharp edges, unlike conventional screws.
• Star Drive Encapsulation : No stripping, with 6 contact points.
• CEE thread : widens the hole to limit splitting.
• W-Cut : Reduces torque for a smoother drive.
• Zip-Tip : No pre-drilling required, ensuring rapid penetration.
• Cutting Pockets : Create a clean hole, reducing the risk of splitting and ensuring accurate drilling.
• ESR-2442 approved for structural applications.
• Climatek coating complies with AC257 code for use in treated lumber.
• Suitable for interior and exterior use including load-bearing beams, framing rails, stair handrails, deck posts, playground equipment and other professional applications.
• Resistors comply with CSA 086-14.
