I am very happy with these wrenches. Our team of 6 cable workers have one and it fits every bolt and nut size we come across. It works with 3 stud terminals for all sizes of stranded wire. I've seen some reviews saying it's not a tight fit, but not all nuts are exactly the same either. It's easy to paint too, I painted mine bright orange as I usually toss them in the weeds. About half the price of Klein, this is a great key.
