Threading that holds the main and alt fuse
I took off a metal sheet that revealed these is there a way I can remove it so I can replace mine on my vehicle a bolt broke off and won’t come out

I don't see a broken bolt in your photo. Not sure what you are asking?

that’s the fuse box from another car it’s cut out I’m trying to get the threading from that one so I can put it in my vehicle I don’t know how to get either of them out

Those terminals are probably clipped in as is the outer casing.
