Features & Benefits

• Heat-treated hardened steel: Provides high tensile strength and high shear strength for demanding construction and woodworking applications.
• Triple-layer ACQ-compatible bronze coating: Provides corrosion resistance for interior and exterior use.
• Deep T-25 six-lobe star drive: Provides a secure driver connection and helps reduce cam-out during installation.
• High-torque drive system: Designed to handle up to 2X the torque of Phillips or square-drive screws while helping extend driver-bit life.
• Under-head cutting nibs: Help the screw self-countersink for a cleaner, more finished appearance.
• Aggressive knurl: Enlarges the hole as the screw is driven, helping reduce splitting and drag while pulling lumber tightly together.
• V-cut thread notches: Cut through wood fibers to promote easier insertion and lower driving torque.
• 17-degree tip: Helps provide faster, more precise starts and reduces the tendency of the screw to walk across the work surface.
• Self-starting design: Allows easier insertion and can eliminate pre-drilling in many applications.
• Aggressive threads: Provide strong holding power and excellent withdrawal resistance.
• Structural wood screw: Backed by certified independent testing under TER 1911-01.
• IBC and IRC compliant: Suitable for applicable construction applications when installed according to requirements.
