Unknown Decking Nail

[mthomas27 (Michael Thomas)]

I havent seen this nail before, ever, and am having a hard time finding out what it is. Seems to be a roof decking nail of some sort. House is in Florida, built in 1995. Any feedback would be appreciated.

Screw Shank Roofing Nails - Greatest Holding Power

Thank you, I guess I didnt think it was one of those due to the flat tip.

It looks like a sheathing nail, not a roofing nail, you can see the roofing nails in the pic, and they are shorter.

Looks like those blunt-tip screw shank nails.

That looks pretty spot on, thank you.

I agree with Scott.
