Counter nuts, also known as Pal nuts and tight nuts, are specially designed self-locking nuts that are similar in shape to hex nuts, but are flatter. This nut uses a one-piece stamped design and has no threads inside, but is equipped with multiple-toothed structures. During installation, these teeth will snap tightly into the bolt, thus achieving a fixing effect.
