MS24665-136 Cotter Pin is a military standard aircraft fastening component designed to provide positive mechanical locking for castellated nuts, clevis pins, bolts, and other drilled fasteners used throughout aircraft structures and mechanical systems. This 100-piece pack is ideal for aviation maintenance, repair, overhaul, and OEM manufacturing applications where reliable fastener retention is required.

Manufactured in accordance with the MS24665 specification, this cotter pin features a nominal 1/16 in. diameter and 1 in. overall length. It is commonly manufactured from corrosion-resistant stainless steel, offering excellent durability, corrosion resistance, and the flexibility necessary for dependable installation in demanding aerospace environments.

The cotter pin is installed by passing it through a pre-drilled hole in a compatible fastener and bending the two legs in opposite directions to create a secure mechanical lock. This proven retention method effectively prevents loosening caused by vibration, cyclic loading, and operational movement. MS24665 cotter pins are widely used in landing gear assemblies, flight control systems, engine accessories, hydraulic equipment, and numerous structural aircraft applications.

As a standard aviation hardware item, cotter pins should be replaced whenever removed during maintenance to ensure continued locking performance and maintain the integrity and safety of the assembly.
