MS21045L6 – Nut – 10 pcs Pack (Replaces MS20365-624C)

Aerospace all-metal self-locking hex nut designed for high-temperature and vibration-prone aircraft applications. It features an all-metal prevailing torque locking element that maintains secure fastening without the use of a non-metallic insert, making it suitable for engine compartments and other harsh operating environments. This part is an approved replacement for MS20365-624C in applicable aircraft maintenance and assembly configurations.

Application:
Aircraft engine compartments, turbine engine accessory systems, high-temperature airframe zones, exhaust-adjacent structures, and other aviation fastening points requiring all-metal lock nuts

Function:
Provides a threaded fastening connection with integrated all-metal locking resistance, maintaining clamp load and preventing loosening under vibration, heat, and dynamic operational stresses
