you can buy 1/2 square to 1/4 hex adapters from dewalt, for torque it claims to have 2000in lbs (220nm) of torque but not sure if that can be trusted. Only thing i am worried about is ordering through amazon i get some protection with the wrench, whereas the driver is on ebay and says in the description, 'out of original packaging for lighter shipping', seems a little weird but probably okay, any thoughts on those points?
