Also known as hitch pin clips and R-clips, these pins are easy to install and remove.

These pins are coiled for more tension than standard wire-snap cotter pins.

Slide the pin through a hole then snap the ring down to lock these pins in place. Also known as click pins.

For parts that spin or are otherwise difficult to access, slide these pins in and tap them with a hammer for a temporary hold. Reposition work, then bend the prongs outward to secure.

The double-head design lets you push or pull these pins from either side of the hole. Once in place there's little chance they will be vibrated out or knocked off.

Twist these rings on to lock pins in place. They don't have the sharp ends of other cotter pins.
