Self-locking nuts are specialized fasteners designed to prevent loosening under vibration or torque. These nuts incorporate a mechanism that creates friction between the nut and the bolt, ensuring a secure fit that resists the forces that typically cause standard nuts to become loose over time. The design may include features such as nylon inserts or deformed threads, which enhance the locking capability and provide a reliable connection in various applications, from automotive to aerospace. By utilizing self-locking nuts, engineers and technicians can enhance the safety and durability of their assemblies, reducing the need for frequent maintenance and inspections.
