How to loosen the rivet nut a bit:
If it is a nut that has not rusted or slipped, find a suitable wrench and turn it counterclockwise.
If not, then：
1. Cola. Directly apply cola to the rusty screws and let it sit for a period of time, you will find that the screws are easily loosened. This is because cola contains carbonic acid in its composition, while iron oxide is the component of rust. The chemical reaction between the two can remove rust.
2. Alcohol+white vinegar+detergent. Add an appropriate amount of water to the bottle, then pour in two bottles of alcohol, two bottles of white vinegar, and two bottles of detergent. Shake well. Pour some onto the screw, let it sit for a few minutes, and then lightly tighten it with a wrench. The rusted screw can be immediately loosened, and it can be easily removed.
3. Use a hammer to forcefully strike. The screw is rusty, don’t use a wrench to tighten it hard, otherwise it will be difficult to screw it off. You should use a wrench to tighten the screw, and then use a hammer to hit the handle position of the wrench a few times with a high frequency. If the rusty parts inside are loosened due to knocking, it will be much easier to tighten again. Alternatively, you can directly hit the nut and knock it around several times, which will also cause looseness between the nut and the screw and make it easier to unscrew.
