stereo ? - power distribution blocks

i'm planning on using one of these for the power wire, but can i also use it for the ground wire as well? there's no difference right?

i need to go 0 ga from battery to disti and out to 4 and 8

same thing for ground

i can just buy two of these and it will work, right?
