Strong-Drive® SDWH TIMBER-HEX Screw
Structural Wood and Engineered Wood Connections Including Ledgers
Designed for structural and general-purpose fastening applications where a hex-head drive is preferred.
Strong-Drive SDWH Timber-Hex screws are 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.
- Sturdy thread design for enhanced holding power
- SawTooth® point for rapid starts, reduced installation torque, and eliminating predrilling in most cases
- Underhead nibs allowing the head to countersink into wood with minimal splintering
- Large washer head providing ample bearing area (0.650" washer head diameter)
- Size identification markings on all SDWH screw heads
- 5⁄16" hex drive for convenient installation
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.
