This is a pack of four (4pcs) of nuts for the headlight mount hinges. These are the nuts for the swivel bolts on these headlights. Each headlight uses 2 of these nuts, so this pack will replace the mount swivel hinges on both headlights. These are brand new, factory OEM, genuine GM parts, not in the original package. These are metric, hex, flange nuts. You will receive 4 nuts per order.
