I am trying to tighten a kitchen faucet bolt (7/16 inch) in a very tight spot. Please refer to the picture.
Standard size wrenches don't fit well enough for me to turn it. I've used a stubby wrench but I can't get any leverage because of the tight spot. I bought a set of flex head rachet wrenches, but they keep slipping off. I also tried a basin wrench, but it keeps slipping off and is very hard to attach.
Do you recommend any other tools that would work? Would an offset wrench work or an adjustable flex head wrench work? I just don't want to keep collecting tools that I won't use!
Thanks for your help :)
