I have found, when using heat, I first heat the screw very hot, then squirt water on it to cool it rapidly. It seems the shock of rapid temperature change breaks the bond. I have been consistently impressed by my 1/4” impact driver. It pops out fasteners that look corroded and seized quite easily. Occasionally nothing works. Then you may have to relocate the whole bracket and redrill the holes. Trying to drill out small stainless fasteners in aluminum with a hand drill is hardly ever successful.
