*For nails inserted perpendicular to the grain. For nails driven parallel to the grain or toe-nailed, the load should not be more than 2/3 of the value in column 5.
A useful rule of thumb for estimating safe lateral loads for nails 12d and smaller is to take ten times the pennyweight.
Lateral load, see sec 2318.3.1 of 1997 Uniform Building Code
