Load Tables
TB — Allowable Loads — DF and SP Lumber Attachment to Steel (Steel Members 16 ga.– 5/16" Thick)
- For use with structural steel members up to 5/16" thick or cold-formed steel members 54 mil (16 ga.) or thicker.
- Minimum steel strength Fu = 45 ksi.
- Standard product available in a black phosphate coating. Mechanically galvanized (N2000) coating available for additional corrosion protection.
- Reference allowable loads are based on tests using 2x (1.5 in.) thick wood members.
- 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.
- 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.
