I agree on the (phillips) screwdriver tips. They sneak up on you and you don't realize that they are rounded off. What I have done for another alternate is to take a dremmel cut off disc, the thinnest one and carefully cut a tiny groove across the head of the screw after first sticking down two small strips of duct tape on both sides of the screw for protection. Just a tiny slot is all that is needed, then take a flat blade screwdriver and try to back it out. First I (gently) tap the screwdriver head with a small hammer (gently) this helps loosen the interface between the steel screw thread and the aluminum. If you have a new phillips screwdriver you might try the (gentle) tap then turn approach first and see what happens. Good luck, I know it is frustrating ! Thumbs up on the drop of oil on the screw threads too !!!
