Frozen set screws and allen head screws

[luvnitro]

I have an MGT and the pin in the rear drive CVA broke oir came out. Anyway, I tried to remove the allen head screw to the cup drive and my allen wrench just twisted like a pretzel. What is the best way to get frozen screws loose? Can the part be heated, would that help. Also what type of allen wrenchs are the best to buy for working on your truck? I need to get a good set, both standard and metric. Thanks for the help anyone.

I use the Associated hex drivers. They're 60 bucks, but you get all of the common metric and standard sizes.

As for the screw...yes...heat should help loosen it up a bit.

Use a soldering iron to heat the part before trying to remove. Use a good hex driver, one that is ground from a drill blank is best.
