Strong-Drive® SDPW™ DEFLECTOR Screw 

The Strong-Drive SDPW Deflector screw from Simpson Strong-Tie is a premium structural fastening solution for connecting non-load-bearing walls to trusses and joists. With tested lateral-load ratings that meet building code requirements, the SDPW screw is value engineered for strength, installation speed and safety. Offset driver bits and a driver extension maximize installation speed and safety while minimizing installed cost. The SDPW’s screw and polymer sleeve permit the naturally occurring differential deflection between the wall and the supporting member without squeaking.

Key Features

  • Deep 6-lobe recess for secure driving
  • Polymer sleeve allows for deflection without squeaks
  • Interior-grade E-coat for dry service applications
  • Offset driver bit (6-lobe) drives SDPW Deflector screw to predetermined screw depth
  • Available in 3 1/2", 5" and 6" lengths

Applications

  • Non-load-bearing partition walls to trusses and joists

Product Includes

  • Retail packs include (1) Offset Driver Bit and (1) 3/8" predrill bit. Mini bulk packs include (2) Offset Driver Bits and (2) 3/8" predrill bits.

Patent Information

  • US Patent 8,458,972

Load Tables

Allowable Shear Loads (F1 and F2) for SDPW DEFLECTOR Screws that Connect a Non-Load-Bearing Partition Wall and the Supporting Member

Model No. Top Plate Allowable Lateral Load (lb.), SPF/DFL/SP (CD=1.6)
Offset = 0"
Gap		 Offset = 3/4"
Gap
0" 1/2" 3/4" 1 1/2" 0" 1/2" 3/4" 1 1/2"
  1. Allowable lateral load was calculated based on a safety factor of 5.0. Loads were increased for wind and earthquake (CD=1.6); no further increases allowed. Reduce when other loads govern.
  2. Per section of 1607.15 of IBC-2018, interior walls and partitions at least 6' in height must resist a horizontal load of 5psf. Screw spacing shall be determined by a designer.
  3. I-joist shall shall have minimum flange thickness of 1 1/8".
  4. The SDPW DEFLECTOR screw is preferably driven with Simpson Strong-Tie offset driver bit for the 3/4" offset installation.
  5. The partition wall top plate-to-stud and top-plate splice connections shall be fastened per applicable building code.
  6. A 0-in. gap may result in load transfer into walls not designed to be load-bearing.
  7. Cells with ‘NA’ represent conditions that should not be built using the SDPW14312 Deflector screws.

  1. Spacings are maximums (inches on-center) based on a 5psf horizontal pressure and short duration (CD=1.6) allowable loads. For other durations, adjust loads and spacing.
  2. In each cell: spacing (in.) for 8' tall/10' tall wall.
  3. Cells with ‘NA’ represent conditions that should not be built using the SDPW14312 Deflector screw.
  4. Spacing for wall heights between 8' and 10' may be interpolated.
  5. Spacing for other loads and wall heights shall be calculated using the Allowable Shear Loads (F1 and F2) for SDPW DEFLECTOR Screws table above.
