What Size Lug Studs Come With the Buyers Products Stake Pocket Spare Tire Carrier

I bought this tire carrier and need to know what the thread pitch is for the 1/2inch press in bolts. I took it to the local hardware store and couldnt find a match. The wheel that I am trying to mount has small diameter holes and I need a smaller diameter lug nut to fit. Thanks,
