GRK RSS Structural Screw Black Steel 5/16 x 3 1/8 100 PC

Black for architectural applications with the same performance of Gold RSS, GRKs RSS. 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.

• No pre-drilling, faster penetration, reduced splitting with a low torque and smoother drive
• Cutting pockets provide a clean hole, reduces splitting, and bore with precision
• Washer style head with star drive: no head stripping
