In a 25k system, securing an apex requires specific components to ensure the integrity and safety of the load. The correct combination is a bolt, a castellated nut, and a cotter pin.

The bolt serves as the primary fastening element that connects the apex to the load. Its strong and robust design is essential for bearing the weight and distributing the load evenly during transport.

The castellated nut is designed with slots or notches that allow for a cotter pin to be inserted. This design prevents the nut from loosening during operation, which is critical for maintaining the security of the apex under various conditions, such as turbulent movement or abrupt changes in altitude.

The cotter pin fits through the slot in the castellated nut and secures it in place, effectively locking it to the bolt and preventing any accidental disengagement.

The other combinations do not meet the necessary structural and safety requirements for securing an apex in an air assault operation. For example, washers, rivets, screws, and tape are not reliable in this context as they do not provide the secure locking mechanism or strength needed to handle the heavy loads associated with aerial operations.
