Hairpin Cotter Pins

Hairpin Cotter Pins, often referred to as hitch pin clips, R-clips, or R-keys, secure the ends of hitch pins by being inserted into a hole at the end of the hitch pin to eliminate the chance of the pin falling out. These are most often found securing pins in wheels, axles, rotary machines and trailer hitches.
