6.8mm ~= .27". Probably a 1/4" hex head. 2 hundredths does seem like a lot
of slop for a hex drive, though.

I just got a 3TTT "Evol" quill stem, mainly for its "moderne" appearance, and discovered that the Allen head screws for clamp and quill are highly non-standard. After spinning a 6mm wrench to no avail, I measured the Allen socket and it came to 6.8mm! ( I pulled out a set of really cheap Allen wrenchs I've had for years and got one to work.)

Question: Is this typical of 3TTT stems in general or just the Evol model?
