A receiver pin is used to secure the receptacle part of a trailer hitch (attached to a vehicle) to inserts such as ball mounts, drawbars, accessory carriers or ornamental receiver plugs. The most common receiver pins are 1/2″ and 5/8″ in diameter. Class II receiver hitches have 1-1/4″ receptacles and use 1/2″ pins. Class III, IV and V receiver hitches have 2″ receptacles and use 5/8″ pins.
