Structural Timber Screws

• Corrosion resistant
• Compatible with treated lumber, however, in areas within 1 mile of saltwater, near swimming pools, in situations involving corrosive chemicals, or in other environments where corrosion is more likely to occur, such as agricultural animal confinement areas, use appropriately sized, stainless steel Big Timber Fasteners of the correct grade and type.

APPLICATIONS

• Log home construction
• Timber framing
• Glulam beams
• Rim beams
• Sill plates
• Stair stringers
• Deck posts
• Fences
• SIP panels
• Post-frame buildings

BENEFITS & FEATURES

• Heat-treated hardened steel for high tensile and shear strength
• Triple-layer ACQ-compatible bronze coating for exterior or interior use
• Performance-enhancing wax coating reduces driving torque for smoother driving
• Deep six-lobe star drive reduces cam-out. Accepts twice the torque of Phillips or square drive while extending bit life
• Integrated washer head for increased pull-through resistance
• Cutting edges under the head for easier self-countersinking
• Aggressive knurling enlarges the hole to reduce splitting, friction, and make wood assembly easier
• V-notches on threads to cut fibers for easier insertion at lower torque
• Type 17 tip for faster, more accurate starts, eliminating skidding and enabling easier insertion without pre-drilling
• Aggressive threads for excellent pull-out resistance
• Independently certified structural timber screw (TER 1907-01) (Acceptable alternative to galvanized lag screws)
• Complies with International Building and Residential Codes
