About a million years ago, I bought a Craftsman hex socket w/bit, 1/4 drive, and then bought individual bits to fit in the socket. I still have them, and they work great on a 1/4 drive torque wrench. Don't know if they still have them. I paid about $4 for the first one, and about $1 for each individual bit.
Sometimes it's worth spending money on a cheap set like this, just for the options they offer
