List,

 

Here's a way to repair stripped screw holes (Especially if an oversized
screw strips) in an aluminum rail that takes less than a minute or two.
"Helicoils" is what they are called. (See attached pic.) 

 

You drill out the hole and tap it, then insert the little coil which
disappears into the tapped threads, and then you're good to go! Maybe
this has been shown on CAUT before, I don't remember seeing it. The new
screw is actually a machine screw with fine threads so it takes a few
more rotations, but this is way better than anything else I've ever
tried. The package shows a bolt, but what actually goes in has a
Phillips head and looks like a normal screw.
