Correct lug nut thread pitch 2013 Sportsman 500 H.O.

Hey guys i just purchased a set of wheels and tires from Discount Tire Direct. Everything is good and came very fast but they sent me 10×1.25 lug nuts and they did not work. Before i call them back to fix this what is the correct size? Should i of gotten 3/8 lug nuts? My quad is a 2013 Polaris Sportsman 500 H.O.

Thanks in advance.
