“That's one tall nail”
I purchased a Craftsman Framing Nailer to work on my fencing project. Unfortunately, keeping this nailer supplied with nails became a challenge at the time I was starting my project. None of the local stores had any in stock of the right type (correct angle, length, nail head, coating, etc.). I ended up finally finding these nails online at Sears but couldn't get them at a store. Apparently, there is a bit of a "nail war" shortage going on out there because of import issues, but I won't digress. It came down to using these nails with the plastic retaining strap. I've actually purchased a few boxes of nails all of different lengths.
I really had to crank up the pressure and striking strength on the nailer to get these nails to be fully seated. I was applying these to either 2x4s or 4x4s (Pressure Treated) and couldn't always get them in but that was more a problem with the wood and the nailer and not the nails, I assume.
Many times a bit of the plastic strap would end up trapped under the nail head itself (I'm using full heads, not clipped, as required by code) and I would have to scrape the plastic residue off the wood afterwards. Not a big deal, but an extra step required on my fencing project. You don't want to see these little yellow plastic pieces clinging to the fence. HA.
