When a split pin is placed in a hole, the head prevents the pin from moving completely. Then, the open ends are bent to secure it in place. Various sizes and finishes are available depending on the application. Features: 1. Split pins are most frequently used to secure clevis pins or castle nuts. 2. Cotter pins are inserted into holes in certain types of fastener systems to secure them in place. 3. When inserted into a hole, the two prongs on the opposite end can be separated and bent outwards to lock the pin. 4. The ends prevent the pin from being pulled out of the hole, so it is important to select a pin with a diameter measurement larger than the diameter of the hole in the fastener being used.
