Power Steering Pulley Lock Nut Size??

I picked up a Saginaw power steering pump from my local auto parts store and it didn't come with a lock nut to hold on pulley. I figured I'd have one in all the bolts I have in my garage but none seemed to fit.

Does anyone know the lock nut size?

I measure 5/8ths. Nut is fine thread with a locking crown and half with. Kind of stange nut indeed.

Just wanted to post an update - The actual thread size is 9/16 -18 (nylon) lock nut. Summit sells them for $4 but it's always best to check a bolt shop. I found the correct one locally for .13 cents
