The MS24665-351 is a steel cotter pin designed to lock drilled fasteners against loosening in aircraft assemblies. This pin passes through aligned holes in castellated nuts and fastener stems, then bends at the prongs to create a mechanical lock. Compliant with MS24665 aviation standard, it prevents fastener rotation on control linkages, landing gear components, and structural connections subject to vibration.

Installation requires inserting the pin through the drilled fastener and bending both prongs outward. Cotter pins must be replaced after removal and reinstallation per aircraft maintenance manual specifications.
