Yes you have the right idea, But the ones I have has a 1/2 in drive hole in them.
I use them mostly in repairing hyd lines on large equipment, but they come in handy doing other jobs.
Ps, remove the other 3 bolts first and loosen the last one then you can turn it by hand.
Yes it is working blind but with the other bolts removed first you can wiggle the compressor
so the bolt turns freely to remove it.
If it's already broken....I can't hurt it.
