ASN52320BH040N - Nut

Part number ASN52320BH040N is a miniature aerospace-standard self-locking flanged hex nut designed for lightweight, vibration-resistant fastening applications in aircraft, avionics, and precision mechanical assemblies. The integral flange provides increased bearing surface area for improved load distribution while reducing the need for a separate washer.

This all-metal prevailing torque locknut is engineered to maintain secure thread engagement under vibration, thermal cycling, and dynamic loading conditions. Manufactured from high-strength alloy steel with a corrosion-resistant finish, it is suitable for compact installations where reliable retention and reduced weight are critical.
