Load Tables

TB — Allowable Loads — DF and SP Lumber Attachment to Steel (Steel Members 16 ga.– 5/16" Thick)

  1. For use with structural steel members up to 5/16" thick or cold-formed steel members 54 mil (16 ga.) or thicker.
  2. Minimum steel strength Fu = 45 ksi.
  3. Standard product available in a black phosphate coating. Mechanically galvanized (N2000) coating available for additional corrosion protection.
  4. Reference allowable loads are based on tests using 2x (1.5 in.) thick wood members.
  5. Use increased allowable loads (CD = 1.6) only when resisting wind or seismic forces. Values must be multiplied by all applicable adjustment factors per the NDS.
  6. Minimum fastener spacing requirements to achieve allowable loads: 4" end distance, 1.5" edge distance, 1.5" between staggered rows, 3" between non-staggered rows, and 4" between fasteners in a row.
