Designed to provide an easy-to-install, high-strength alternative to through-bolting and traditional lag screws. The Strong-Drive SDWS Timber Screw (Exterior Grade) 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.
- 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 (0.75in 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
