I used these nails in my Porter Cable nailer. I was working on the Habit for Humanity project and we were rebuilding the deck. Screws are my preferred option, but timing was key. The holding power of these nails is amazing. I've used them for some temporary bracing and even removing nails from fairly old wood was incredibly difficult. They're a little air pressure sensitive (at least on my nailer), but that's a small price to pay. Best holding power of any nail I've used except for the old fashioned spiral shank.
