It's not common, but you can definitely get bolts with non standard key sizes. I've got a couple on my car that are the same thread and head size but have different Allen key sizes. Might be worth checking between the ISO and JIS versions because I know an ISO and JIS M8 bolt use different spanner sizes.

Cheers, will take a look. I know it will fit the seatpost clamp I have on one of my bikes as that has a bigger bolt. Just a case of working out what search terms to use!
