Stock 5/16-24

You can convert to 5/16-18, but you have to buy new studs and you _may_ 
have to grind them down a bit to clear the hub flange. I've used studs 
that are course threat on one end and fine on the other for this job. 
Those are hardware store / auto parts counter common parts (the 
course/fine combo studs)
