Cotter Pins - 304 Stainless Steel Used to prevent accidental loosening of fasteners304 Stainless steel is corrosion-resistant, durable, and suitable for freshwater environmentsCommonly used with castle nuts to prevent the nut from vibrating loose Description Cotter pins, also called split pins or cotter keys, are bent pins with a rounded head that are slid into a hole. Once inserted into the hole, the two ends are bent into different directions deforming the pin, so it cannot be easily removed from the hole. While cotter pins come in many shapes and sizes, the most common is the split pin variety. Cotter pins are used with castle nuts to lock the nut onto a bolt and prevent it from spinning loose accidentally. They are usually made of a soft metal, so they can be bent by hand or with pliers to make them difficult to remove. It is common to see a cotter pin reused after being removed if it does not break during removal. This is not a good practice, however; the pin should be replaced with a new pin as metal fatigue will prevent the pin from performing to standards once bent again.
