AnchorMark S3-TTT Decking Screws - 1,000 PCE

SKU: 6636901

AnchorMark S3-TTT Decking Screws feature innovative under-head threading that pulls boards down while distributing tension across multiple points, ensuring a cleaner, tighter finish with superior stability. The asymmetrical thread design minimises screw-in resistance for faster, smoother installation, while delivering exceptional grip and pull-out strength that withstands sustained pressure. Built for decking applications where lasting performance matters.

Advantages of this screw include:

  • 304 / 316 stainless steel offers excellent corrosion resistance, even in hardwoods with high natural acidity or in coastal environments.
  • Pyramid shaped drill tip reduces splitting and ensures precise positioning in hardwood.
  • The added under-head thread provides strong pull-down force and a flush, stable finish.
  • The small, stepped head countersinks smoothly for a clean and discreet appearance.
  • Asymmetrical thread and high-lubricity coating reduce drive-in torque while maintaining strong pull-out strength.
  • Compression thread eliminates gaps and creaking for a long-lasting connection.
  • Includes a SIT®20 drive bit for maximum power transfer and wobble-free screwing.
  • Available in 316 stainless steel for superior durability in outdoor and high-moisture environments.
