These nails are too weak to be useful for Hardie siding jobs. They will bend and collapse often when they encounter harder areas such as knots or older lumber. They actually bend back upon themselves forming a complete 180 degree bend. They especially collapse when passing through 2 layers of Hardie material such as installing the Hardie trim.I found that having a Bostich Stick Nailer with 2" nails handy and a pair of pliers to remove the bent coil nails will make the job go faster.
