MS24665-155 Cotter Pin is a military standard aircraft fastening component designed to provide secure secondary locking for castellated nuts, clevis pins, bolts, and other drilled fasteners used throughout aircraft structures and systems. This package contains 100 cotter pins intended for aviation maintenance, repair, overhaul, and manufacturing applications.

Manufactured in accordance with the MS24665 specification, this cotter pin is engineered to withstand the vibration, cyclic loading, and demanding operating conditions commonly encountered in aerospace environments. The split-pin design provides a simple and highly reliable locking method that helps prevent fasteners from loosening or becoming disengaged during aircraft operation.

After installation through the pre-drilled hole of a compatible fastener, the legs are bent in opposite directions to create positive mechanical retention. Cotter pins are widely used in landing gear assemblies, flight control linkages, engine accessories, hydraulic systems, and numerous other critical aircraft applications where secure fastening is essential for operational safety and system reliability.

As a standard aviation hardware item, the MS24665-155 cotter pin should be replaced whenever removed during maintenance to ensure continued locking performance and compliance with accepted aircraft maintenance practices.
