Strong-Drive® WSV SUBFLOOR Screw (Collated)

Strong-Drive® WSV SUBFLOOR Screw

On This Page

2", 2 1/2" and 3" models coming soon. Please contact Simpson Strong-Tie for details (800) 999-5099.

Simpson Strong-Tie has re-engineered its popular subfloor screw to reduce driving force and increase installation speed. The new Strong-Drive WSV Subfloor screw has been developed for fastening subfloor sheathing using the Quik Drive® auto-feed screw driving system.

Key Features

  • Redesigned tip and thread pattern provides easy starts and up to 25% less torque while driving1 — makes for up to 20% faster driving2
  • Less installation torque also means less wear on tools
  • Deep 6-lobe recessed ribbed head provides clean countersinking and more secure bit retention for fewer cam-outs
  • The holding power of WSV screws reduces the gaps between the joist and subfloor that cause floor squeaks
  • WSV screws can be easily backed out, allowing for future access to floor cavities
  • 6-lobe T25 drive bit (replacement bit BITTX25)

1. Test data shows the Strong-Drive WSV Subfloor screw requires up to 25% less driving torque in single-material LVL.
2. Test data indicates the redesigned WSV thread pattern will result in 20% faster screw installations.

Applications

  • Subfloor and sheathing projects

Load Tables

WSV — Allowable Shear Loads for DFL/SP and SPF/HF

  1. Table values are based on attachment of a 1 1/2" side member to a 1 1/2" main member of the same species and grade.
  2. Table values are based on the 2018 NDS, CD = 1.0. Values shall be multiplied by all applicable factors, such as duration of load, etc., except where noted.
  3. Specific Gravities (G) assumed: DFL G = 0.50, SP G = 0.55, SPF G = 0.42.
  4. The spacing of applied uniform loads to a multi-ply member shall not exceed 24 inches on center.

WSV — Allowable Pull-Through and Withdrawal

  1. Use the lower of the pull-through or withdrawal values to determine axial design value.
  2. Screws must be installed normal to the side grain of the wood main member with the screw axis at a 90° angle to the wood fibers.
  3. The main framing member must be wood having a minimum specific gravity of 0.50 for DFL and SP main members, and 0.42 for SPF and HF main members. DFL is Douglas fir–larch. SP is southern pine. SPF is spruce-pine-fir. HF is hem-fir.
  4. Withdrawal values, W, are in pounds per inch of the thread penetration in to the main member. Wmax is the maximum reference withdrawal value.
  5. Allowable loads are shown at the wood load duration factor of CD = 1.0. Loads may be increased for load duration up to CD = 1.6.

WSV — Allowable Loads Comparison of Common Fasteners Used to Attach Truss Plies Together

  1. Table values are based on attachment of a 1 1/2" side member to a 1 1/2" main member of the same species and grade.
  2. Table values are based on the NDS, CD=1.0. Values shall be multiplied by all applicable factors, such as duration of load, etc. except where noted.
  3. Specific Gravities (G) assumed: DFL G = 0.50, SP G = 0.55, SPF G = 0.42.
  4. For a series of loads to be considered a uniform load, the loads must be applied no further apart than 24" o.c.
  5. Assumes nail Fyb = 100 ksi.
  6. WSV212S and WSV3S withdrawal values based on testing per AC233.
