GRKs RSS Rugged Structural Screw is made of specially hardened steel to provide you with high tensile, torque and shear strength. The sharp threads and points bite instantly into the material (including hardwood), reducing the splitting effect due to smaller shanks.
GRK Cabinet screws were designed specifically for uses in cabinet construction and installation. All Cabinet screws are manufactured in a #8 gauge (4 mm) diameter. Lengths range from 1"1/4(30 mm) to 3"1/8(80 mm
