Product Details

The 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 2018 and 2021 IRC® and IBC® code requirements for most common wood framing applications.

Key Features

  • SawTooth® point ensures fast starts, reduces installation torque and eliminates the need for pre-drilling in most applications
  • Bold thread design provides excellent holding power
  • Under-head nibs offer greater control when seating the head
  • Large low-profile washer head provides maximum bearing area (3/4 in head Dia)
  • Size identification on all SDWS screw heads
  • Six-lobe T40 drive provides positive engagement that makes the screw easy to drive and improves bit life
  • Double-barrier coating provides corrosion resistance equivalent to hot-dip galvanization, making it suitable for certain exterior and preservative-treated-wood applications
