Big Timber #15 CTX Construction Lag Screws

MATERIAL: Heat Treated Hardened Steel
HEAD: Round Washer Head
DRIVE: Star T-30

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
