Everbilt 3/4 in. Zinc-Plated External Hitch Pin

Also known as a hairpin cotter or R-clip, Crown Bolt's hitch pin is used to secure the ends of round shafts most commonly on tractors or heavy equipment. Insertion into a hole depends on the straight leg entering the hole and the curved leg pressing down upon outer diameter of the shaft. Compared to cotter pins, hitch pins are easier to remove and are reusable. Some types have a clip for extra security. Zinc plating offers some corrosion protection.
