I have thousands of nutserts in stock, installation tools start from $80, up to $1200 for the full automatic hydro/pneumatic tools; can do rivnut install within 2 seconds. With the hand tool, you will feel it after the 5th rivnut but doable. If you want the complete fastener/tool thing, it will be $110, or I can do the loaner tool and just the rivnuts/button heads for $30. Just PM me and we can go from there.
