MS21042L3 – Nut

Aerospace all-metal self-locking hex nut designed for secure fastening in aircraft structural and system assemblies. It features an all-metal prevailing torque locking element, providing reliable resistance to loosening without the use of a non-metallic insert. This makes it suitable for use in environments with elevated temperatures, vibration, and continuous cyclic loading where standard nylon-insert lock nuts may not be appropriate.

Application:
Aircraft airframe structures, engine accessory installations, control linkages, landing gear components, avionics and system mounting points, and other aerospace fastening locations requiring all-metal locking hardware

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
