I have one or two of these tools and I would like to get a full set 8 to 22mm -- problem is I don't known the official name --- it is bi-hexagon ie 12 point not a square brake adjuster.

The Stanley type number appears a Goggling blind alley, in the dark recesses of my brain I recall the name Aviation Wrench but a Google on that get nowhere.
