What are the Benefits of Using Cotter Pins?

Using cotter pins can help to keep your machines safe and secure. They are designed to withstand wear and tear due to vibrations and can help to prevent rotary parts from becoming loose and falling off during use.

How Do Cotter Pins Work?

Cotter pins are inserted into holes in a castle nut or bolt with a hole, which then holds it in place on the shaft it is attached to. The cotter pin is then twisted to secure it in the hole and the ends of the pins are bent over to prevent it from coming loose. This ensures the fastener is securely locked in place.
