DATIAN (DT) Fastener is famous for producing quality heavy hex nuts. We, one of the professional heavy hex nut manufacturers, have a in house full line heat treatment machine used to improve the hardness and mechanical properties of heavy hexagonal nuts in order to serve different high requirement areas. The heavy duty hex nuts standard we listed below are most ASTM A194/A563 and ANSI/ASME B18.2.2 heavy hex nuts. Compare to finished hex nuts, the heavy hex bolt nut carry higher grade and slightly wider and thicker diameters to meet the greater length of thread engagement and better resistance to stretching or widening.

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.
