That sentence was based on my assumption that because he suggested using a socket he thought the issue was trying to remove the handlebar from the stem, in which case a socket could be used. My apologies to Shp4man if he took offense as that wasn't my intent.

If you want to refer to both these tools as simply "sockets" that's your choice. Personally, I'll continue to draw a distinction between the two so as to avoid confusion. I've always heard them referred to as 3/8" or 1/4" hex drivers.

As for the subject of this thread, I have heard of 3ttt Record stems as OEM in French bikes, I believe, but have never seen one that was marked as 22.0 or any other mark to indicate it was not 22.2. I believe they were all made with a 26.0 handlebar clamp.
