A stainless steel cotter pin is a metal fastener with a distinctive U-shape, or split, that is inserted through a hole to secure components like clevis pins or castle nuts. It consists of a wire that is folded to form a head and two prongs, which are then bent outward to lock it in place. Made from corrosion-resistant stainless steel, these durable pins prevent fasteners from loosening under vibration and are widely used in automotive, industrial, and mechanical applications.
