Cotter Pins

LINE DCotter pins are simple, yet essential fastening devices used to secure components and prevent unintended movement or separation. They consist of a straight metal pin with a looped or bent end, resembling the letter "U" or hairpin. The straight section of the cotter pin is inserted through a pre-drilled hole in a shaft or joint, while the looped or bent end is bent back or spread apart to lock it in place. Cotter pins are commonly made of stainless steel, brass, or other durable metals to provide strength and resistance to corrosion. They are often used in mechanical assemblies, automotive applications, machinery, and equipment to secure various parts such as bolts, clevis pins, and shafts. The versatility, simplicity, and reliability of cotter pins make them an effective and widely used fastening solution in many industries, ensuring the stability and safety of mechanical systems.
