MS21044N10 – Nut (Alt. to MS20365-1018)

Aerospace self-locking hex nut with nylon insert designed for secure fastening in aircraft structural and system assemblies. The integrated nylon locking element provides prevailing torque to resist loosening under vibration, thermal cycling, and dynamic loading while maintaining consistent clamp force. This part serves as an approved alternative to MS20365-1018 in applicable aerospace installations.

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

Function:
Provides a threaded fastening connection with a nylon insert that creates frictional resistance on the bolt threads, maintaining clamp load and preventing loosening under vibration and operational stresses
