Aerotight is best known for its all-metal self-locking nuts, which are designed to resist loosening in applications exposed to vibration, movement or repeated use. Unlike nylon insert lock nuts, Aerotight nuts maintain their locking performance without non-metallic components, making them suitable for higher-temperature environments and applications where durability is important. Reusable and available in a range of materials and finishes, Aerotight locking nuts are a trusted choice across engineering, manufacturing and maintenance applications.
