How to repair cross treaded screw used to secure back cover

My back cover screws seem to be cross threaded and screw in about 60% of the way. I do not want to use any more force which may strip the head.

I did back off and screw, turned backwards till I felt a click, then started to screw it down. Unfortunately it stopped before it completed its full travel. It sticks up a 1 mm. I did try to blow hole out with air and inserted a spudger point to try to remove metal fillings.

If the screw is damaged, replace it. If the threads that the screw turns into are damaged, I would put a small amount of silicone sealant or other type adhesive glue of your choice on the screw, then thread push into place. When dry it should hold sufficiently and wont be very hard to turn out if the need should arise.

The screw is fine but the aluminum case thread was cross threaded. Because of the change in angle of the screw it only went in 60% of the way. I would not go any further without stripping the head. I used a Dremel cutoff blade and cut a slit in the screw . This acted to cut into the aluminum hole and I got 3 additional turns but still insufficient. Next I cut the screw in half to shorten it with Dremel. I also chamfered the tip to make a lead in and dress the threads. This worked great. I will have to be careful when I remove and insert the next time.

The above method would not work in my situation but thanks for your response.
