To remove the bolt and nut without damaging the threads, you can follow these steps: Use the appropriate tool: Choose the right wrench or socket wrench, make sure it matches the size of the bolt and nut, and is able to apply the appropriate force. Position of bolt and nut: Place the wrench over the nut, and ensure that the contact point of the wrench is tightly fitted to the hexagon or square end of the nut. This provides better force transfer and reduces the risk of thread damage. Apply appropriate force: Use the wrench to turn counterclockwise and apply moderate force in the direction of removal. When applying force, it should be stable and continuous, and do not use too much force to prevent thread damage. If the bolt or nut still cannot be removed: If the bolt or nut has stubborn rust, you can try to spray a special thread loosening agent or lubricant, wait for a moment, so that it penetrates into the thread, in order to remove. If the bolt and nut cannot be removed, gently tap the bolt and nut with the appropriate knocking force or impact tool, such as a rubber mallet or impact screwdriver, to loosen them. After the removal is complete, check the status of bolts and nuts. If they are damaged or deformed, replace them in time. It should be noted that for bolts and nuts with special threads or materials, special tools or methods may be required for disassembly. Please perform operations according to specific conditions and follow relevant safety regulations.
