I bought this to use in my Freeman PFN1564 finishing nailer. The instruction manual lists nails at 34 degrees, and the product description says it's nails at 33 to 35 degrees. I had a heck of a time trying to get it to drive nails in, it missed over 50% of the nails. I checked the box to see what angle the nails were at and there was no angle printed on the box. So I pulled out my handy digital goniometer and measured the angle. These are 24 degree nails. Be careful if you don't use them in a Bostitch nailer!
