    I’m looking for an adapter for my torque wrench. It has 1/4 inch attachment but a need a converter to take it to 1/2 inch. I’m struggling as every adapter I find steps down from 1/2 to 1/4 but not they other way around. Does this do it? Ie has a 1/4 inch female end to 1/2 male end so I can attach a tool that has a 1:2 inch square whole? Answer:
    Yes, the 11030003 would be suitable.

    Can this adapter be used on an impact wrench? Answer:
    It would depend on the setting. For low torque settings the standard adapter will work fine, but for high torque, we would recommend using the impact adapter.
