Cotter Pins

Our collection of cotter pins includes a wide range of sizes and styles designed to securely lock fasteners and clevis pins in automotive, marine, and industrial applications. These split pins are commonly used in axle nuts, shaft retention, and trailer hardware to prevent loosening from vibration or movement. Manufactured from durable materials like zinc-plated steel or stainless steel, our cotter pins offer corrosion resistance and long service life in harsh environments. Available in various diameters and lengths to support both OEM replacement and universal repair needs.
