AN363-720 – Nut (Alt. to MS20365-720C)

Aerospace all-metal self-locking hex nut designed for high-strength fastening in aircraft structural and mechanical assemblies. It features a prevailing-torque all-metal locking element that maintains secure thread engagement without the use of a non-metallic insert, making it suitable for applications exposed to vibration, thermal cycling, and elevated temperatures. This nut serves as an interchangeable alternative to MS20365-720C in approved aerospace installations.

Application:
Aircraft airframe structures, engine accessory installations, landing gear assemblies, control system linkages, and other aviation fastening points requiring all-metal self-locking hardware

Function:
Provides a secure threaded fastening connection with an all-metal locking feature that maintains clamp load and prevents loosening under vibration, heat, and dynamic operational stresses
