Technical Features

  • Climatek Corrosion-Resistant Coating: Steel screws are coated with Climatek finish, enabling safe use in outdoor environments and with treated lumber without premature corrosion.
  • W-Cut CEE Thread Profile: The no-split CEE thread design reduces wood-splitting during fastening, maintaining substrate integrity across framing and decking applications.
  • Star Drive Head (T25): The zero-stripping star drive geometry maximizes bit-to-fastener contact, reducing cam-out and driver wear; a T25 bit is included in the bucket.
  • Self-Drilling Point: Creates its own pilot hole and countersink, eliminating the need for pre-drilling in standard wood and plastic substrates and accelerating installation speed.
  • Dust-Ejection Design: Thread geometry transports material dust away from the edge of the screw hole, producing a cleaner bore and tighter seating.
  • 720-Count Contractor Bucket: High-volume packaging at 1.57 lb total weight supports continuous job-site use without frequent restocking.
  • Treated Lumber Approved: Coating is rated for use with ACQ and other treated lumber, broadening compatibility for deck and outdoor framing projects.

Applications

  • Residential and light commercial wood framing
  • Deck construction and decking board fastening
  • General woodworking assemblies
  • Plastic substrate fastening
  • Indoor and outdoor installations requiring corrosion resistance
  • Treated lumber structures
