AN320-7 – Nut – 10 pcs Pack

Aerospace castellated (slotted) nut designed for use with drilled shank bolts and cotter pin locking systems. It provides a positive mechanical locking method that ensures the fastener remains secured under vibration, cyclic loading, and operational stresses. Manufactured to AN specifications, it is widely used in aircraft assemblies where safety-wire or cotter pin retention is required. Supplied in a 10-piece pack for maintenance and repair use.

Application:
Aircraft structural assemblies, landing gear components, control system linkages, engine accessory installations, and other aviation fastening points requiring castellated nuts with cotter pin safety locking

Function:
Provides a threaded fastening connection that is mechanically locked using a cotter pin through the bolt hole, preventing rotation and loosening under vibration and dynamic loads
