Split Pin

A split pin, also known as a cotter pin or split cotter, is a simple and widely used fastening device. It consists of a metal pin with two tines that are bent apart to secure it in place. Here's a brief description of a split pin: Design: A split pin typically has a cylindrical or partially cylindrical shape, with a head at one end and two straight or slightly curved tines extending from the other end. Function: The primary function of a split pin is to secure fasteners, such as bolts or nuts, in place. It prevents unintended loosening by passing through a hole in the fastener and being secured by spreading the tines apart on the opposite side. Installation: To install a split pin, it is inserted through the aligned holes in the fastener and the component it is securing. The tines are then bent or spread apart to prevent the pin from sliding out, providing a simple and effective means of fastening. Removability: One of the advantages of a split pin is its ease of removal. By bending the tines back together, the pin can be easily extracted, allowing for quick disassembly of components. Applications: Split pins are commonly used in various industries, including automotive, construction, and machinery. They are employed in situations where a secure and removable fastening method is required. Variations: Split pins come in different sizes to accommodate various fastener dimensions. Some may have additional features such as a second head or a loop for easy handling.
