Big Timber #9 x 5 In. Bronze Star Drive Trim Head Wood Screw (1 Lb.)

Compatible with treated lumber, but areas within one mile of saltwater, near swimming pools, exposure to corrosive chemicals, or other areas where corrosion is more likely to occur, such as livestock confinement, use the proper size, grade and type of Big Timber Stainless Steel Fasteners.

• Heat-treated hardened steel for high tensile strength and high shear strength
• Triple layer ACQ compatible bronze coating for exterior or interior use
• Wax coating enhances performance, reducing the torque for a smoother drive
• Deep six-lobe star drive recess reduces cam-out end load
• Handles 2X the torque as Phillips or Square Drive while extending the life of the bit
• Under-head cutting nibs to aid in self countersinking
• Precision cut knurl enlarges hole to reduce splitting and drag to help draw lumber together
