I work in the stainless steel business and we use nutserts daily, i don't really see a difference in what was posted above. We do use air powered tools to install them though. I hate the metric ones, and i also am a huge anti stainless hardware person too,

i hate stainless bolts etc.
but, they are a great tool to use when you can't get to the back of something or really anywhere for that matter for a clean easy to disassemble part.
