NAS679-A4 – Nut – 25 pcs Pack

Aerospace all-metal self-locking nut designed for high-reliability fastening in aircraft structural and mechanical assemblies. It features an all-metal prevailing torque locking element that provides secure resistance to loosening without the use of a non-metallic insert, making it suitable for high-temperature, vibration-prone environments. Supplied in a 25-piece pack for maintenance, repair, and production use in certified aviation applications.

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

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