My jeep has a lot of torx bolts that I need to remove and then replace some of. A while ago I bought a single torx socket from ACE hardware that is made from two steel pieces of metal. The other day I got a set of torx bits from Autozone because I needed to use my reward zone points, the set I got from autozone are all singe pieces of metal that appear to be cast steel and don't feel too strong.
Which type of socket will hold up better when used with an impact driver?

Thanks.
