MS20365-820C – Nut

Aerospace all-metal self-locking hex nut designed for use in aircraft structural and mechanical assemblies where high strength and vibration resistance are required. The nut features a prevailing-torque all-metal locking element that maintains secure thread engagement without the use of a nylon insert, making it suitable for elevated-temperature environments and critical aerospace applications. It is widely used in certified aircraft systems requiring reliable long-term fastening performance.

Application:
Aircraft airframe structures, engine compartments, landing gear assemblies, control system linkages, and other aerospace fastening points exposed to vibration and elevated temperatures

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