The MS24665-421 is a military standard cotter pin designed for aerospace fastening applications requiring positive mechanical retention and reliable locking of aircraft hardware components. Manufactured in accordance with the MS24665 specification, this fastener is commonly used in aircraft assemblies, control systems, landing gear components, clevis fittings, bolts, nuts, and other applications where secondary locking protection is required.

The cotter pin design allows the legs to be bent after installation, creating a secure locking method that prevents unwanted movement, rotation, or loosening of retained components during aircraft operation. This simple and effective retention method is widely used throughout aviation maintenance procedures where dependable hardware security is essential.

Manufactured to aerospace standards, the MS24665-421 provides consistent fit, reliable installation, and durability for demanding aircraft service environments. It is suitable for OEM maintenance, repair, and overhaul (MRO) operations where approved replacement locking hardware is required.

Supplied in a 50-piece pack, the MS24665-421 provides a practical quantity for aircraft maintenance facilities and hardware inventory management.
