This 5/8 in. hitch pin from Buyers Products makes it faster and easier to connect a ball mount to a receiver tube. Instead of a cotter pin, it features an integral spring clip that rotates to lock in place. Designed to fit a 2-in. receiver tube, it is zinc-coated to stand up to the elements. The hitch pin assembly is packaged for retail and can be ordered in master cartons of 50.
