I changed my mind. Maybe it is a Woodruff key.
Yeah, the dimension IS awfully close to a 1/8" key. I hadn't noticed that and it's certainly not standard to find that in a metric hub, but it wouldn't be the first time a manufacturer mixed and matched as they saw fit.
So assuming they used a 1/8" key in a 10mm shaft, the question becomes how deep did they set that key? Keyslots are cut to 1/2 the key depth at the chord. If they did that then the measurement across the shaft to the key face should be 11.33mm.
Alternatively, if they just cut the slot to the depth of a conventional 3mm key, it would protrude further and the measurement would be 11.63mm.
You measured 11.51mm. Hmmm.
