Cotter / Split Pin

Cotter Pins, also known as Split Pins, are simple mechanical fasteners used to secure bolts, shafts, clevis pins, and other assemblies. They are manufactured to ASTM, DIN, and ISO standards in carbon steel, stainless steel, or brass. Once inserted, the legs of the pin are bent apart to lock the component in place, providing a cost-effective and reliable fastening solution. Available in various sizes and materials with plated, galvanized, or stainless finishes, they ensure durability and corrosion resistance. They are widely used in automotive, agricultural, machinery, marine, and general engineering applications.
