Hairpin Cotter Pins

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

Strong-Hold Hairpin Cotter Pins

A coil makes a stronger grip than standard hairpin cotter pins to prevent accidental release.

Clip these pins onto grooved shafts and clevis pins with retaining ring grooves.

Strong-Hold Wire-Snap Cotter Pins

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

Wire Snap Cotter Pins

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

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

Cotter Pins

Also known as split pins, these have one prong slightly longer than the other so they’re easy to open. Bend prongs outward to secure.

Bow Tie Cotter Pins

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.

Hammer-Set Cotter 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.

Wedge-Lock Cotter Pins

Slide these heavy duty pins into the through-hole in a clevis pin, then hit them with a hammer to wedge the prongs open.

Hairpin Clip Assortments

Clip these pins onto grooved shafts and clevis pins to keep components in place.
