They are rather expensive, but these nails are superb. The galvanizing is very thick and consistent. The nails don't jam, and mine arrived all intact in collation and undamaged. Using these nails will require you to reducing loads by 10% according to Simpson because they are 1/2" shorter than the 10d nails they specify, but frankly the time saved is well worth it.
