Self-Locking Counter Nuts

Self-locking counter nuts are a type of nut that features a built-in locking mechanism to prevent them from loosening due to vibration or other external forces. These nuts typically have a nylon insert or metal insert that creates friction when tightened onto a bolt, providing resistance against loosening. This design helps to ensure that the nut stays securely in place, reducing the need for frequent re-tightening and maintenance. Self-locking counter nuts are commonly used in automotive, aerospace, and other industrial applications where vibration resistance is important.
