Self-clinching self-locking nuts are a type of nut that is installed by crimping the end of the nut into a hole. This creates a secure connection and prevents the nut from loosening. The nut also has a self-locking feature that helps to prevent the nut from backing out under vibration or torque. Self-clinching self-locking nuts are typically made of steel or stainless steel and are available in a variety of sizes and finishes.
