To be fair, that’s a very open ended question. I mean, what kind of bolt are we talking about? A standard lag bolt? If so you don’t tighten it! That’d be a trick question! You tighten the nut. Same thing applies with car wheel bolts. Tricky tricky!

Is it a hex bolt that also has a cross head? How tight are we talking?

I’m just going to assume bolts of lightning and Usain Bolt are off the table.
