Table Notes

  1. Allowable loads have not been increased for wind, seismic or other factors.
  2. Screw spacing and edge distance shall not be less than 3 x d. (d=nominal screw diameter)
  3. The allowable loads are based on the steel properties of the members being connected, per AISI Section E4.
  4. When connecting materials of different thicknesses or tensile strength (Fu), the lowest applicable values should be used.
  5. The nominal strength of the screw must be at least 3.75 times the allowable loads.
  6. Penetration of screws through joined materials should not be less than 3 exposed threads. Install and tighten screws in accordance with the screw manufacturer's recommendations.
  7. Screw shear capacities are based on allowable strength design (ASD) and include a safety factor of 3.0.
  8. Applied loads may be multiplied by ¾ for seismic or wind loading, per AISI A 5.1.3
  9. Loads are for attachment of DPLC2 Drift Clip to stud only. It is the responsibility of the designer to check the bending in the short leg of this clip and its connection to the structure members, depending on the direction of forces.
