The most used term for the wrench is a "Crows Foot Wrench".
If you purchase one, the best have the drive opening and the wrench opening that goes on the nut in perfect vertical alignment. Some are not aligned, are offset, and you have to use them properly to obtain proper torques.
Here is a previous string/discussion with lots of info.
