Merely clamp the vice grips securely onto the rounded nut, making certain that the jaws chew deep into the steel. With a agency grip established, apply regular strain to show the nut counterclockwise. The vice grips’ highly effective jaws will generate sufficient friction to interrupt the nut free, even when its edges are severely deformed.
Alternatively, if the rounded nut defies the vice grips’ may, take into account the chilly chisel and hammer method. This method entails utilizing a chilly chisel to create a notch within the nut’s floor. Place the chisel perpendicular to the nut and strike it sharply with a hammer. Repeat this course of across the nut’s circumference, steadily making a collection of notches. As soon as the notches are deep sufficient, insert a flat-head screwdriver into one in all them and use it as a lever to pry the nut unfastened. The chilly chisel’s forceful impression will weaken the nut’s construction, permitting you to extract it with relative ease.
