The MS24665-351 cotter pin is a military-standard aircraft fastener used to secure clevis pins, bolts, and other pinned connections by preventing them from loosening or backing out during vibration and operational loads. It is a simple but critical locking component widely used in aircraft assemblies, including landing gear, control linkages, and mechanical joints.

This version is supplied in a 100-piece pack, making it suitable for maintenance, repair, and overhaul (MRO) operations. The pin is designed for single-use locking, where the legs are bent after installation to create a secure mechanical stop.

Manufactured from cadmium-plated carbon steel, it provides good corrosion resistance and durability in aviation environments, including exposure to moisture, vibration, and temperature changes.
