Cotter pins, also known as split pins, are essential fasteners used to prevent nuts and bolts from loosening due to vibration or rotation. As a specialized cotter pin manufacturer, we understand the critical role these small components play in ensuring the safety and reliability of assemblies across industries such as automotive, aerospace, construction, and heavy machinery. Our manufacturing capabilities allow us to produce cotter pins that meet stringent international standards, including DIN, ISO, and ANSI. We utilize high-quality raw materials, such as stainless steel 304 and 316 for corrosion resistance, carbon steel for high strength, and brass for electrical applications. The production process begins with cold heading, where wire is formed into the basic shape, followed by CNC machining to achieve precise dimensions and chamfers. Forging is employed for larger sizes or when enhanced mechanical properties are required. Our multi-station cold heading machines ensure high-volume output with minimal material waste, while our CNC lathes and machining centers guarantee tight tolerances. Surface treatments like zinc plating, hot-dip galvanizing, or black oxide are applied to enhance corrosion resistance and appearance. We also offer custom packaging and labeling to streamline your inventory management. With a commitment to quality and customer satisfaction, we serve clients worldwide, providing expert technical support and rapid prototyping services. Whether you need a few thousand or millions of cotter pins, our scalable production ensures on-time delivery and competitive pricing.
