What is the reason for the screw spinning in place and not coming out?

It may be due to the screw post inside being broken, making it impossible to unscrew. Below are the precautions for installing license plates: 1. Do not reduce the number of installation screws: License plates should be installed properly, otherwise it will be considered as not installing the motor vehicle license plate in accordance with regulations and will be penalized. For example, current cars have 4 installation holes each for the front and rear license plates, so when installing the screws, you must install all 8 screws; missing even 1 is not allowed. 2. Do not install license plate frames randomly: License plate frames should not be installed randomly. For example, the license plate frames that 4S shops give for free, which have vehicle sales advertisements on the top and bottom, cannot be used according to the new regulations. 3. Incorrect hanging: The position where the license plate is hung should not affect the safe driving of the motor vehicle or the recognition of the license plate. For example, hanging it diagonally may result in the checkpoint camera not being able to fully capture the license plate.
It's really frustrating when a screw just spins in place and won't come out. I've encountered this situation many times over decades of car repairs. The most common reason is that the threads on both the screw and the hole are worn out, what we call 'stripped threads'. Over-tightening or rust can flatten the threads, causing the screw to get stuck and not come out. Tool issues are also quite common - if the screwdriver bit is loose or the wrong size, it can't grip the screw head properly and just spins uselessly. For solutions, first spray some WD-40 or lubricant and wait a few minutes to loosen the rust. If that doesn't work, try using pliers to grip and pull the screw out, or switch to specialized screw extraction tools. Regular maintenance like cleaning screws and applying lubricant can prevent such issues. Don't underestimate screw problems - loose screws in critical car components can cause serious accidents. I've fixed several cases where screws were the culprit, so timely resolution is crucial for safety.
I once encountered the issue of a screw spinning in place when I tried to replace a car seat screw. It was probably due to the screw being made of too soft a material or being the wrong size, not matching the hole properly. It would rotate but wouldn't come out, making the effort feel wasted. Later, I looked into it and realized that the screw hole might have been clogged with dust or rusted, or perhaps the wrong-sized tool was used. I sprayed some lubricant and gently pried it, and it gradually loosened. As a preventive measure, I learned to choose the right screwdriver and check the thread condition before installation. Loose screws in a car shouldn't be ignored as they can affect the stability of the entire component. Avoid driving too fast before fixing the issue. With each DIY attempt, I've become more attentive to details.
