Are you referring to the lower bolt that goes through the strut's lower bracket and control arm? If so, use a sawzall to cut the bolt on both ends just inside the strut bracket, then get a new bolt and nut from the dealer.
When you tighten that nut, the car must be sitting at normal ride height. That means leaving it loose, bouncing the car on the ground, then crawling underneath to tighten the bolt, (unless it's sitting on a drive-on hoist). When you tighten that bolt, it captures and holds the rubber bushing in the lower control arm. If you do that with the suspension hanging down, it will put that bushing into a permanent twist when you lower the car to the ground. That will greatly reduce the life of the bushing.
