Let down keys

[Run Time]

Would someone be kind enough to tell me the distance across the hex flats (- the middle section of the key ) - in the same manner as fitting a spanner/wrench. I do appreciate there is more than one manufacturer but it’s the type sold with a yellow handle that I am interested in.
many thanks .
