Hitch pins do not carry a specific class rating. Typically, if it is the correct length and diameter for your hitch (6 inches long x 5/8 inch thick) it will automatically have a rating appropriate for its application. Usually hitch pins have a shear strength rating far in excess of their load requirements.
I did pull one from inventory and take measurements with a precision caliper. The diameter of the clip hole is 0.28 inch. The diameter of the pin itself is 0.18 inch.
In the event that you need only the spring clip, and not the entire hitch pin and clip set, I want to point out that the spring clip only is available separately, as part # 55515. The diameter of this spring clip is 0.15 inch.
I have attached a brief video that provides these details.
