Ed,
I think this is what he is talking about. You can get them in carbon or ss. I have used them in my machine shop and they do work very well. They make a tool to set the pins once they are screwed in. I make a threaded installer that screws into the ID and has an OD that stays inside the pins, then use the tool to set the pins.
