Sunex Tools Impact Socket - 1 1/16in., 1/2in. Drive Deep, Model# 234D
I bought a larger version of this, 1&7/8" for torquing hitch ball nuts to over 400 lbs.ft. It works great for this purpose and shows no signs of wear--granted, I haven't done all that many, but it performs well for what I needed it for.
