ANSI/ASME B18.2.2 Heavy Hex Nuts

Heavy Hex vs Hex

The first thing to declare is that both heavy hex nuts and finished hex nuts belong to the hexagon nut classification. Simply put, the difference between them is that heavy hex nuts have larger widths across the flats and heights of the same nominal size. This gives heavy hex nuts higher load retention and tensile strength. This also explains why heavy hex nuts can be heat treated to achieve higher hardness.
