If you should find yourself in a tight situation, needing a wrench that you just simply do not have on hand, then this life hack might be exactly what you are looking for.
Instead of using fancy equipment, this life hack video shows us how to get the job done with something that you probably have on hand, a run of the mill nut and bolt.
By simply adjusting the nut to the size of the head of the bolt that you need to get undone, the nut and bolt combo can act as a homemade wrench on the spot.
Check out the video below that shows the process off. This might especially come in handy if you find yourself with an odd sized bolt or one that is a little bit rounded off.
