Designed to provide an easy-to-install, high-strength alternative to through-bolting and traditional lag screws. The Strong-Drive SDWS Timber screw is ideal for the contractor and do-it-yourselfer alike. It is code listed under IAPMO UES ER-192 and meets 2015 and 2018 IRC® and IBC® code requirements for several common wood framing applications.


Features


  • 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 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 T40 drive provides positive engagement that makes the screw easy to drive and improves bit life (replacement driver bit — BIT40T-134-RC)

  • U.S. Patent 9,523,383

  • 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.


    Product Includes
