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. For connections with mixed species, use the loads for the species with the lower specific gravity.
  5. Engineered wood must have a minimum modulus of elasticity grade 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 (lb./in.) Reference Allowable Withdrawal, W (lb./in.) Reference Maximum Withdrawal, Wmax (lb./in.) Reference Pull-Through, (lb.)
DFL/SP SPF/HF DFL/SP SPF/HF DFL/SP SPF/HF
#10 x 2 1/2 CSVZ212 1.50 121 94 180 140 174 154
#10 x 3 CSVZ3 1.50 180 140
  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 modulus of elasticity grade of 1.55E and 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

Condition Minimum Distance or Spacing (in.) Reduction Factor
Edge Distance Perpendicular to grain loading 3/4 0.91
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
Parallel to grain loading 2 1.00
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.
