AN310-5 – Nut – 25 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 secure fastening in aircraft structural and mechanical assemblies exposed to vibration, cyclic loading, and operational stresses. Manufactured to AN standards, it is commonly used in certified aviation applications requiring safety-wire or cotter pin retention. Supplied in a 25-piece pack for maintenance and production use.

Application:
Aircraft airframe structures, landing gear assemblies, 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 operational loads
