How do you remove smooth cap nut?

To remove a smooth cap nut, first ensure you have the right size socket or wrench that fits snugly over the nut. Apply penetrating oil to help loosen any rust or debris. Turn the nut counterclockwise while applying steady pressure; if it’s stubborn, use a breaker bar for extra leverage. If the nut is still stuck, consider using pliers or a nut splitter as a last resort.
