Cotter Pins


A cotter pin is a low cost and simple locking mechanism that is usually used with a matching nut or bolt. They are made from bent steel wire and are a great way of securing two parts together.

Cotter pins are inserted into a pre-drilled hole and then the ends of the pin are pulled apart until they lock on to the material on the reverse side. They are especially effective for attaching wire to fences or posts.
