Cotter Pin

The cotter pin, also known as a spring pin, is a widely used mechanical fastening component. They are typically made from cylindrical metal and have one or more openings, which give them spring elasticity. The primary function of this pin is to secure and connect parts, ensuring the stability of the equipment. Once inserted into the hole, the pin tightly locks into place, preventing parts from moving or loosening.

The open design of the cotter pin offers excellent elasticity, making it easy to remove and reinstall. They have different types, including standard, spiral, and locking pins. Each type has its characteristics, depending on the opening shape and location.

When using a cotter pin, it is important to ensure that the pin size matches the hole diameter. To avoid damage, the pin should be carefully inserted using pliers rather than hammering it in.

They are commonly used to fasten and adjust parts in mechanical and electronic devices such as automobiles, furniture, and industrial equipment.
