You can use a crescent wrench, or pipe wrench. Both are adjustable to fit the nut you are working on.
because the bolt is tight with an adjustable wrench and usually an adjustable wrench isn't strong enough so I would use a socket wrench but if the socket wrench doesn't get the nut loose for you then try a skateboard key (skate tool) to loosen the nut but if that doesn't work I don't know what to tell you other then to visit a skatepark because they will explain why the nut wont come off
what the hex a wrench? Hex wrench is short for hexagonal wrench, that is a wrench or spanner designed to fit a certain size nut or bolt.

When the wrench is fully seated on the nut or bolt, and the other end is secured with another wrench.
