About this product
GRK's RSS™ Rugged Structural Screw is made of specially hardened steel to provide you with high tensile, torque and shear strength. Its sharp threads and points bite instantly into the material (including hardwood), reducing the splitting effect due to smaller shanks. Its Cutting Pockets provide a clean hole and reduces splitting, and bore with precision.
