When it comes to self tapping screws, I think most of us are still familiar with them. In our daily lives, they exist in a wide range of places, and when we look around, they are everywhere. But sometimes, after using the self tapping nail for a long time, it will rust. So what if the self tapping nail rusts and cannot be unscrewed?
1. Wrap the cotton cloth around the rusty screw that needs to be loosened.
2. Pour cola onto the cotton cloth, and then pour an appropriate amount of cola onto the cotton cloth that wraps around the rusty screws.
3. Use wire pliers to remove the screw, let it stand for a few days, and then use wire pliers to slowly remove the screw.
