5/8 X 18 is not a fine thread. 5/8 X 24 would be a fine thread and I just went thru this at Ace Hardware today. I needed 5/16 X 24 nuts and they only had 3 when I needed 4. Never fails!

Its fine thread says right on package i bought and fits perfect. There is more than one fine nut..18 threads per inch verse 24 threads per inch
