Screw shear values are based on the SSMA Screw Table with the following notes:   

  1. The allowable loads are based on the steel properties of the members being connected, per NASPEC with 2004 supplements.
  2. The nominal strength of the screw must be at least 3.75 times the allowable loads.
  3. Values include a 3.0 factor of safety.
  4. Penetration of screws through joined materials should not be less than three exposed threads. Screws should be installed and tightened in accordance with the screw manufacturer's recommendations.
  5. Allowable loads indicated on the table(s) are for force in single direction only. The designer shall use the combined forces check as required by NASPEC with 2004 supplements if more than one force is applied to the connection. 
  6. The designer shall check the bending in the short leg of this clip.
