Thread size for 3/4 ton

Hi I need the stud or nut size for the wheel studs on a 72 K 20. I forgot my sample part at home and I need to buy some today!

Thanks for your reply!

Thanks Jud,
I paid .73 each for 9/16 lug nuts at Pioneer Wheel and Tire. They have the best prices for trailer brakes and parts about 50% less than Northern for brake stuff last time I checked.

Re: Thread size for 3/4 ton

Bud,

I buy all my trailer stuff there but hadn't thought about them for these. Do you have to drive all the way down there to mpls or will they send stuff? The fuel to get there would be a dealbreaker for me.

Here is a hub I rebuilt with the ones from Oreillys
