No Nut - Going Nuts

Does anyone know what size nut is used to hold the lever on the valve stem of an Apollo 1-1/2" seacock...? I've purchased several hoping to find the right size and you know - ended up using a crescent wrench...:huh:

Called Conbraco... Was told it is a 7/16" - 20 UFT. I'll try and post if it works...
