How To Tighten A Stripped Bolt
Copper wire, which can usually be purchased at your local hardware store, is also a good option. You can separate the strands, fold them over, and place them inside the bolt hole. After you repeat this a few times you should be able to tighten down the bolt. The copper will bite into the threads which will keep your bolt snuggly in place.

Spray a bit of penetrating oil onto the bolt. With a hammer, tap the extractor into the hole until it's firmly seated, then use a pair of pliers or a wrench to turn the extractor counterclockwise, and the bolt should back out.

Stripped screws are caused by using the incorrect tools in the first place, and also by user error. Some things that will cause a screw to become stripped include: Using poor quality tools. Working too fast and without enough care.
Try to pick a wrench that is the closest size to the bolt and try different combinations of coins to get a snug fit. If the wrench is too small you can take a long nut and a bolt, screw the nut onto the bolt and tighten the bolt around the nut you want to tighten or loosen.
Pull Back. Put the tip of a flathead screw driver (or anything firm and flat) behind the screw-head, and while you unscrew with a screwdriver, pull the screw head toward you, helping the screw to back out as you're turning the driver. (Sue, I think this method will work best for you.)
Helicoils designed to be put into dry holes do not use any form of loctite or thread seal. A helicoil when inserted properly will have movement inside hole they are inserted into.
