One of the most annoying things that can happen in a project is a stripped allen screw. It can throw off the whole project and cause a lot of stress and wasted time. But don't worry, there is an easy way to fix this problem. You can use a few different methods to get the stripped bolt out of your way.
First, clean the screw head so that you can see what is going on. Then, take a tool such as pliers or a screwdriver and apply pressure to the screw head to try to create movement. If you can, then turn the screw counterclockwise to remove it. If you cannot, then you can try to lubricate the screw head with oil to help make it easier to grip.
You can also try to hammer the screw out of the hole with a hammer or an impact wrench. This can work if there are still grooves in the screw head that provide traction for your tool.
Another option is to use a drill to create a new indentation in the screw head. This can be done by using a screw extractor kit to attach a bit to your drill and then drilling a hole 2/3 smaller than the size of the Allen screw. This will give your screwdriver a good grip in the stripped screwhead and allow you to turn it counterclockwise to remove it.
You can also try to heat up the screw head with a torch to warm it up and loosen it. This is a good option if you have a torch around but remember that this method can be dangerous and it may not work on all types of materials.
