This is not to skew the discussion but to point toward sources of the 7mm - to my experience, 7mm is common in automotive applications, especially brake systems. Auto part store and the automotive tool selection may be good places to look. SK-Facom sells a nice T-handle 7mm. (French company Facom bought the former US company SK Wayne).
Back to bikes I am assuming the 7mm size is more a function of standard design practice; that is, bolt head diameter defines the hex recess size.

The 7 mm hex (allen wrench) has always been curious to me. Hardly anybody sell it in a package and it can be bought only separately(See Sears Dept. Stores). Maybe it has to do with the # 7..very lucky number. I have several of them and I have a piece of yellow electrical tape wrapped around them so I can find it immediately. I always wondered why the Italian used this unique size for the stem quill. The No. 7 .... Hhmmm maybe it is a Catholic, Italian, Pope thing. All I know is I carry one with me on every ride. Call me superstitious.
Happy New Year,
