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

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.

An extra loop locks these cotter pins more securely than other pins, so they can't vibrate out or be knocked off.

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

Also known as safety pins, these are easy to install and remove. Tension keeps them closed.

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.
