Strong-Drive® CSV Construction Screw 

Strong-Drive® CSV Construction Screw

On This Page

The CSV Construction screw is a versatile, multi-purpose fastening solution for a variety of interior applications. With its underhead nibs, low-torque threads and fast-start point, the CSV Construction screw drives effortlessly and is ideally suited to be countersunk into today’s wood or engineered-wood materials. Available in convenient quantities, CSV Construction screws are offered in select sizes for fastening a variety of projects.

Key Features

  • Low-torque threads allow up to 35% more screws to be driven on a battery charge
  • Ribbed-head design countersinks easily and provides a clean, finished appearance
  • High-low point provides fast starts
  • Optimized threads for dimensional lumber
  • Provides corrosion resistance for interior wood and engineered-wood applications
  • T25 6-lobe driver bit included (replacement driver bit BIT25T-2)

Applications

  • General-purpose interior, wood-to-wood and engineered-wood applications

Product Includes

  • T25 6-lobe driver bit

Load Tables

Allowable Shear Loads
Size x Length (in.) Model No. Thread Length (in.) DFL/SP Reference Allowable Shear Load (lb.) SPF/HF Reference Allowable Shear Load (lb.)
Side Member Thickness (in.) Side Member Thickness (in.)
1.5 2 1.5 2
#10 x 2 1/2 CSVZ212 1.50 106 83
#10 x 3 CSVZ3 1.50 173 99 131 80
  1. Allowable loads 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; For in-service moisture content greater than 19%, use CM = 0.62.
  3. Loads are based on installation into the side grain of the wood with the screw axis perpendicular to the face of the member.
  4. Loads are based on tests of connections made with same species as main and side members.
  5. Engineered wood must have a minimum grade of modulus of elasticity value of 0.80E and have a minimum equivalent specific gravity at least 0.50 to use the DFL/SP values or 0.42 to use the SPF/HF values.
Allowable Withdrawal and Pull-Through Loads
Size x Length (in.) Model No. Thread Length (in.) Reference Allowable Withdrawal, W (lb./in.) Reference Maximum Withdrawal, Wmax (lb.) Reference Pull-Through, (lb.)
DFL/SP SPF/HF DFL/SP SPF/HF DFL/SP SPF/HF
#10 x 2 1/2 CSVZ212 1.5 121 94 180 140 174 154
#10 x 3 CSVZ3 1.5 180 140
  1. The tabulated Reference Allowable Withdrawal design value, W, is in pounds per inch of the thread penetration into the side grain of the main member.
  2. The tabulated Reference Maximum Withdrawal design value, Wmax, is in pounds where the entire end thread length is embedded into the side grain of the main member.
  3. Reference withdrawal design values, W and Wmax, are shown at CD = 1.0. Loads may be increased for load duration per the building code up to CD = 1.6. Tabulated values must be multiplied by all applicable adjustment factors from the NDS; For in-service moisture content greater than 19%, use CM = 0.70.
  4. Embedded thread length is that portion of the end threads in the main member including the screw tip.
  5. Reference Pull-Through values are based on pull-through of a 1 1/2"-thick side member.
  6. Engineered wood must have a minimum grade of modulus of elasticity value of 1.55E and have a minimum equivalent specific at least 0.50 to use the DFL/SP values or 0.42 to use the SPF/HF values.
Connection Geometry

Parallel-to-grain loading 1/2 1.00
End distance Perpendicular-to-grain loading 4 0.91
Parallel-to-grain loading 4 1.00
Spacing between fasteners in a row Perpendicular-to-grain loading 2 0.75

Spacing between row Perpendicular-to-grain loading Non-staggered row 1 0.75
Staggered rows 1 1.00
Parallel-to-grain loading Non-staggered row 1 0.88
Staggered rows 1 1.00
  1. Edge distances, end distances, and spacing of the screws must be sufficient to prevent splitting of the wood, or as required by this table, or when applicable as recommended by the structural composite lumber manufacturer, whichever is the most restrictive.
  2. Allowable shear loads shall be multiplied by the applicable tabulated reduction factors when used in the corresponding geometry.
