Strong-Drive® SDWS FRAMING Screw 

Strong-Drive® Exterior Wood Screws

This product's information may differ depending on the category of use. You are currently viewing details related to Strong-Drive® Exterior Wood Screws. You can also view product information related to the category: Fasteners for the Timber Drive™ System

The SDWS Framing screw is designed and load-rated for replacing 16d, 10d and 8d nails in framing applications. The SDWS Framing screw is superior to nails in holding power and pull-out resistance. 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.

The screw has a SawTooth® point that makes for fast installations with reduced torque without predrilling, and its specially designed head countersinks easily to provide a clean, flush finish. The T25 bit holds the 6-lobe recess tightly for more secure drive control. Available in 2 1/2", 3", 3 1/2" and 4" lengths for a variety of uses.

Key Features

  • Washer head with underhead box nibs provides increased bearing in structural applications and provides clean and easy countersinking
  • SawTooth® point ensures fast starts, reduces installation torque and eliminates the need for predrilling in most applications
  • The 6-lobe drive provides positive bit engagement resulting in easier installations and longer bit life
  • Quik Guard® coating provides protection in indoor and outdoor applications

Applications

  • Multipurpose wood-to-wood and engineered-wood applications, including framing, indoor/outdoor projects

Product Includes

  • Driver bit BIT25T-2-R2

Patent Information

  • US Patents 9,523,383; 11,181,138

Load Tables

SDWS Framing Screw — Allowable Shear Loads for Sawn Lumber

Length (in.) Model Side Member Thickness (in.) Main Member Penetration (in.) Reference Allowable Shear Load (lb.)
SP DFL SPF/HF
  1. All applications are based on full penetration into the main member. Full penetration is the screw length minus the side member thickness.
  2. Allowable loads are shown at the wood load duration factor of CD = 1.0. Loads may be increased for load duration per the building code up to a CD = 1.6. Tabulated values must be multiplied by all applicable adjustment factors per the NDS.
  3. For minimum fastener spacing requirements for both side and main members, see the Spacing Requirements Figure and Table below.
  4. For in-service moisture content greater than 19% use CM = 0.70.
  5. Screws must be installed straight into the side grain of the wood main member with the screw axis at a 90° angle to the wood fibers.

SDWS Framing Screw Spacing Requirements

  1. Table loads must be multiplied by adjustment factor of 0.93.
  2. Table loads must be multiplied by adjustment factor of 0.91.
  3. For axial loading only, use the following minimum dimensions: end distance = 2 1/4", edge distance = 7/8", spacing parallel to grain = 1 5/8", spacing perpendicular to grain = 7/8".

SDWS Framing Screw — Reference Withdrawal Design Loads, W (lb/in.)

Model Fastener Length (in.) Thread Length (in.) Reference Withdrawal Design Loads, W (lb/in.) Max. Reference Withdrawal Design Loads, WMAX (lb.)
SP DFL SPF/HF SP DFL SPF/HF
  1. The tabulated reference withdrawal values (W) are in pounds per inch of the thread penetration into the main member.
  2. The tabulated reference withdrawal values (Wmax) are in pounds where the entire thread length must penetrate into the main member.
  3. Tabulated reference withdrawal values (W) and (Wmax) are shown at a CD = 1.0. Loads may be increased for load duration per the building code up to a CD = 1.6. Tabulated values must be multiplied by all applicable adjustment factors from the NDS as referenced in the IBC or IRC.
  4. Values are based on the lesser of withdrawal from the main member or pull-through of a 1 1/2" side member. For in-service moisture content greater than 19% use CM = 0.65.

SDWS Framing Screw — Allowable Shear Loads for Wood Structural Panel Side Member

  1. Allowable loads are shown at the wood load duration factor of CD=1.0. Loads may be increased for load duration per the building code up to a CD=1.6. Tabulated loads must be multiplied by all applicable adjustment factors per the NDS.
  2. WSP side members for tests was oriented strand board (equivalent specfic gravity = 0.50).
  3. All applications are based on full penetration into the main member. Full penetration is the screw length minus the side member thickness.
  4. Screws must be installed straight into the side grain of the wood main member with the screw axis at a 90° angle to the wood fibers.

SDWS Framing Screw — Allowable Pull-Through Loads for Wood Structural Panel Side Member

  1. Allowable loads are shown at the wood load duration factor pf CD=1.0. Loads may be increased for load duration per the building code up to a CD=1.6. Tabulated loads must be multiplied by all applicable adjustment factors per the NDS.
  2. WSP side members for tests were oriented strand board (equivalent specfic gravity = 0.50).
  3. For connections with 15/32" and 23/32" thick OSB side members, the lesser of withdrawal loads from the main and pull-through loads from WSP side member shall be used in design.
