• Heat-treated hardened steel for high tensile strength and high shear strength
• Triple Layer ACQ Compatible Bronze Coating for Exterior or Interior use
• Deep Six-Lobe Star Drive Recess reduces cam-out end load
• Handles twice the torque as Phillips or Square Drive while extending the life of the bit
• Built-in washer head for increased pull through strength
• Under-head cutting nibs to aid in self countersinking
• Aggressive knurl enlarges hole to reduce splitting and drag to help draw lumber together
