Wrenches are one of those tools where, when you need one, there’s not much else you can do if you’re missing it.
It’s pretty impossible to use your fingers to tighten a bolt up past a certain point, anyone who’s tried will know.
But just because you’re missing a store-bought wrench doesn’t mean you don’t have the ability to make your own, and it’s super simple to do; all you need is a somewhat longer screw with a good nut on it and you’ll be able to use that!
