The Simpson Strong-Tie® Strong-Drive® SDWS™ Timber screw is designed to provide an easy-to-install, high-strength alternative to through-bolting and traditional lag screws. This screw is ideal for the contractor and do-it-yourselfer alike. It is code listed in IAPMO UES ER-192 and meets IRC® and IBC® code requirements for most common wood framing applications. The 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.

  • SawTooth® point ensures fast starts, reduces installation torque and eliminates the need for predrilling in most applications
  • Bold thread design provides superior holding power
  • Underhead nibs allow for head to drive flush to surface with reduced splintering
  • Large low-profile washer head provides maximum bearing area (0.760-in. head dia.)
  • Size identification on all SDWS screw heads
  • 6-lobe T40 drive provides positive engagement that makes the screw easy to drive and improves bit life (replacement driver bit — BIT40T-134-R2)
  • Length: 4 in.
  • Color: Tan
  • Quantity: 50 per package
