A cotter pin is a simple but critical fastener used to secure castellated nuts, clevis pins, and other components. It consists of a wire formed into a semicircle with a pointed end and a head. After insertion through a hole, the ends are spread apart to lock the pin in place, preventing nuts from backing off or pins from sliding out. Cotter pins are essential in safety-critical applications such as wheel bearings, linkage pivots, and other areas subject to vibration. A missing, bent, or damaged cotter pin can allow a nut to loosen, leading to component failure or safety hazards. This replacement pin is manufactured to exact size and material specifications. Installation requires proper insertion and bending of the ends. Always use a new cotter pin when reassembling; they are not designed for reuse.
