At one point when I first started building sand rails I also bought a bunch of throw away cheap wrenches that if I lost or broke it wasn't a big loss. I still have several of these wrenches. They were made in India and turned out to be a lot better then I thought they would be. They don't flex or strip so the metal/steel was a lot better then I thought they would be. I was surprised at the quality, only thing cheap about them was the price. Because of the price I didn't feel bad at all about grinding some of them so they were thinner. I have often used them for removing jam nuts. It would be worth your time to shop around for some of the cheap wrenches and do as I did, cut or grind them so they serve your purpose.
