Heavy Hex Nuts, Grade 2, Zinc Plated

Heavy Hex Nut, Grade 2

Compared to standard nuts, Heavy Hex Nuts offer added strength from increased thread engagement, which is due to their thickness. The bearing surface is larger because they are extra wide. Hot Dip Galvanized Heavy Hex Nuts are tapped oversize and should only be used with Hot Dip Galvanized bolts and screws. See our Heavy Hex Nut Dimensions reference chart.
