Key Features

  • New — Patented SawTooth™ point ensures fast starts, reduces installation torque and eliminates the need for predrilling in most applications
  • Bold thread design provides superior holding power
  • Under-head nibs offer greater control when seating the head
  • Large low-profile washer head provides maximum bearing area (0.75" head dia.)
  • Size identification on all SDWS screw heads
  • 6-lobe T-40 drive reduces driver-bit cam-outs, resulting in easier installations and longer bit life

Double-barrier coating provides corrosion resistance equivalent to hot-dip galvanization, making it suitable for certain exterior and preservative-treated wood applications, as described in the evaluation report.

Applications

  • Structural wood-to-wood and engineered-wood connections including ledgers
