Split Cotter Pin Manufacturer | Custom Forged & CNC Machined

Split Cotter Pins, also known as split pins or cotter pins, are essential fasteners used to secure the position of mechanical components. Their simple yet effective design consists of a metal wire bent into a U-shape, with two tines that can be spread apart after insertion through a hole to lock the pin in place. This mechanism prevents axial movement and ensures that nuts, bolts, and clevis pins remain securely fastened even under heavy vibration or dynamic loads. In automotive, aerospace, and industrial machinery, Split Cotter Pins play a critical role in safety and reliability. Our company leverages advanced manufacturing processes to produce Split Cotter Pins that meet the most demanding specifications. We integrate forging, cold heading, CNC machining, and stamping to create pins with precise dimensions and consistent mechanical properties. Our 8 forging machines, including 630T and 300T models, allow us to form robust pin heads and tines, while our 10 multi-station cold heading forming machines enable high-volume production with excellent material utilization. Over 100 CNC lathes, 50 CNC machining centers, 20 turning-milling composite machines, and 10 centering machines ensure that every Split Cotter Pin is machined to exact tolerances. We also offer a variety of surface treatments, such as zinc plating, hot-dip galvanizing, and passivation, to enhance corrosion resistance and extend service life. Understanding the diverse needs of global customers, we specialize in customized production of non-standard Split Cotter Pins. Whether you require a specific length, diameter, material grade, or coating, our engineering team can tailor the product to your application. We serve industries ranging from automotive and aerospace to construction and marine, where reliability and safety are paramount. Our commitment to quality is reflected in every Split Cotter Pin we manufacture, ensuring peace of mind for our clients worldwide.
