I bought these primarily to install crown molding/mouldings on a bathroom remodel and to install some shoe lasts over an LVP floor in a detached garage apartment. I thought the SS might be worth the extra investment to ensure corrosion/rust stains are no longer a problem in the future due to humidity (from steam etc in the bathroom and intermittent air conditioning when guests are not using the room). It hasn't even been a year since the original install but still no problems (and no reason to expect any problems with these pin nails as I left a couple of these on a windowsill outside my shop a few months ago and no signs of rust still have.). I've used a Metabo HPT NP50A nail gun with them and there haven't been any glue or other compatibility issues.
