Material Heat-treated hardened steel Sizes #14 x 1ʺ to #17 x 16ʺ Head Round Washer Head Drive Star Drive Common Uses Include • Log Construction• Timber Frames• Laminated Beams• Girders• Ledger Boards• Stair Rails• Deck Posts• Fencing• SIP Panels• Pole Barns Benefits and Features: • 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 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• V-Cut notches on threads to cut fibers for easier insertion at lower torque• Type 17 tip for faster precise starts which eliminate “walking”and provides easier insertion without pre-drilling• Aggressive Thread for great withdrawal strength• Structural Lag Screw backed by certified independent testing (TER 1907-01) (Acceptable alternative to galvanized lag screws)• International Building Code and International Residential Code Compliant CTX Product Options DIAMETER/DRIVE LENGTH AVG.
