Aluminum 2024 T4 lock nuts are strong with good fatigue resistance and a good strength-to-weight ratio. They are also known as an economical purchase commonly used on aircraft.

Aluminum 2024 is composed of aluminum, manganese, and copper with copper as the primary element. To achieve the T4 temper, metal is solution heat-treated and naturally aged. A T4 temper gives Aluminum 2024 the highest ductility compared to other Aluminum 2024 variants.
