Square nut

Square nuts, Hot dipped galvanized steel

Nut size (A.K.A. diameter) is the size bolt that the nut is used with. The same is true of the thread count. Thus a 1/4"-20 nut fits a 1/4"-20 bolt.

Important Note: Due to the plating thickness, only hot dipped galvanized bolts should be used on hot dipped galvanized nuts.
