Backer-On screws are designed for attaching HardiBacker fiber cement backerboard to wood or light gauge steel studs. Ideal for use in high moisture areas such as baths and showers, sink backsplash, countertops and floors. Backer-On's self-drilling point eliminates the need to pre-drill, and a special patented thread design reduces installation torque and provides superior holding power. A special rib design under the head countersinks for flush seating in board, providing a smooth surface for tile. Backer-On screws feature a corrosion resistant finish which prevents rust from bleeding into tile. Backer-On screws conform with ANSI A108.11 for cement board attachment and install with a standard screwgun and a #2 square drive bit (included with product).
