I have this 7/16" hex nut (in front) and I tried to order in amazon an adapter that can make my 1/4 hex bit torque screwdriver drive it. When I received the package. It was all wrong. The 7/16" was the size of the hex bit and the 1/2 is the size of the square wrench (I need all to be hexagon or 6 sides, not 4 sided).
What is the proper way to do this?
I also bought adapter for 1/4 hex to 1/2 hex thinking the male size was 1/2 size (when it fact it was 7/16" size)
