I have actually also used a 3/8" deep-well socket, 1/4" drive and socket wrench, but the socket must be 6-point. Add a short extension if you need to, but hold the end tight. You might be able to get more leverage using a socket wrench with a cheater pipe on the end. Don't get real crazy with the cheater pipe though. Spray the bleeder screw threads down with a rust dissolving solvent first.
If you do try to use heat, be real careful with the tip/flame because you could catch brake hose on fire!
