Strong-Drive® SDWS FRAMING Screw 

Strong-Drive® SDWS FRAMING Screw

The SDWS Framing screw is designed and load-rated for replacing 16d, 10d and 8d nails in framing applications. The SDWS Framing screw is 0.160" in diameter and superior to nails in holding power and pull-out resistance. It is code listed under IAPMO UES ER-192 and meets 2012 and 2015 IRC® and IBC® code requirements for several common wood framing applications.

The screw has a SawTooth™ Type-17 tip with serrated threads that makes for fast installations with reduced torque without predrilling, and its specially designed head countersinks easily to provide a clean, flush finish. The T-25 bit holds the 6-lobe recess tightly, reducing cam-out and head stripping.

Key Features

  • Large head with underhead box-nibs provides increased bearing in structural applications and provides clean and easy countersinking (0.44" head dia.)
  • SawTooth™ Type-17 tip for quick starts with no predrilling
  • Serrated threads reduce installation torque for easier driving
  • The 6-lobe drive reduces driver-bit cam-outs, resulting in easier installations and longer bit life
  • Quik Guard® coating provides protection in indoor and outdoor applications

Applications

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

Product Includes

  • Driver bit BIT25T-2

Load Tables

SDWS Framing Screw — Allowable Shear Loads for Sawn Lumber

  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. Minimum fastener spacing requirements to achieve table loads; 2" (SDWS16212) and 3" (SDWS16300) end distance, 1/2" (SDWS16212) and 1" (SDWS16300) edge distance, 7/16" between staggered rows of fasteners, 1" between non-staggered and 4" between fasteners in a row.
  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 degree angle to the wood fibers.

SDWS Framing Screw — Allowable Withdrawal Load in Sawn Lumber

  1. The tabulated reference withdrawal design values (W) are in pounds per inch of the thread penetration into the main member.
  2. The tabulated reference withdrawal design values (WMAX) are in pounds where the entire thread length must penetrate into the main member.
  3. Tabulated reference withdrawal design 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-degree 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 was 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.
