Why does Simpson Strong Tie require 2-1/2" nails for the H2.5A connector when the rafter is only 1-1/2 inches thick? The nails into the rafter protrude 1".
The requirement is listed in the table on page 271 of the Simpson Strong Tie 2019-2020 catalogue. I am nailing the H2.5A connector into the double top plate and the rafter.
