Note N/A
  1. Screws shall be #10-16 Buildex® or equivalent, with an ultimate shear capacity per screw of 1400 lbs.
  2. Table to be used by qualified engineers only.
  3. To determine the capacity of any given connection, compare the jamb and head values, and use the minimum. For example, if a 16 gauge,50ksi jamb is used with a 3.625" HDS 18 gauge, 33 ksi head, the design value for F1 is the minimum F1 value of 1680 lbs for the jamb and 673 lbs for the head. Therefore, the design value is 673 lbs.
  4. For F1 and F2 occurring at the same time, use the squared interaction equation: (f1/F1)^2+(f2/F2)^2<=1.0.
