HEX FLANGE NUTS

Our Hex Flange Nuts combine a conventional hexagonal nut body with an integrated flange, creating a larger bearing surface beneath the nut. This design allows the clamping load to be distributed over a wider area, helping reduce localized pressure on the mating surface and providing a more stable fastening connection. Compared with conventional hex nuts, the integrated flange can also eliminate the need for a separate washer in many suitable applications, helping simplify assembly, reduce the number of loose components, and improve installation efficiency. These characteristics make Hex Flange Nuts a practical choice for automotive components, machinery, equipment manufacturing, sheet metal assemblies, electrical equipment, industrial products, and general mechanical fastening applications.

Carbon Steel Materials for Reliable General-Purpose Performance

Our Hex Flange Nuts are manufactured from 1010 and 1035 carbon steel, providing a practical balance of mechanical performance, machinability, durability, and cost efficiency. Available mechanical property grades include ISO 898-2 Class 6 and Class 8 for metric applications and SAE J995 Grade 2 and Grade 5 for inch-based applications. The available grade range allows buyers to select an appropriate nut according to the required mechanical performance and, importantly, to match the nut with the corresponding bolt grade to ensure compatibility throughout the complete fastening assembly.

Larger Bearing Surface for Better Load Distribution

The integrated flange is one of the key functional advantages of this nut design. By extending the bearing surface beyond the standard hex nut body, the flange helps distribute clamping forces over a larger contact area. This can be particularly useful when fastening components with relatively thin, soft, or easily marked surfaces where concentrated contact pressure may be undesirable. The flange also helps maintain a stable contact interface during tightening. For production environments where installation speed and component reduction are important, the ability to combine the nut and bearing function into a single component can offer an additional practical advantage.

Manufactured to DIN & ASME Standards

Our Hex Flange Nuts are manufactured according to recognized international dimensional standards, including DIN 6923, ASME B18.2.2, and ASME B18.16.4. The combination of metric and inch specifications makes these flange nuts suitable for customers serving different international markets and working with different engineering standards.

Black, Zinc Plated & Hot-Dip Galvanized Finishes

To meet different application environments and corrosion protection requirements, Hex Flange Nuts are available in Black, Zinc Plated (ZP), and Hot-Dip Galvanized (HDG) finishes. This range allows customers to select the finish according to the actual service environment rather than using a single surface treatment for every application.

Designed for Efficient Industrial Assembly

Hex Flange Nuts are particularly valuable in production environments where assembly efficiency, consistent clamping, and reduced component count are important. Because the flange is permanently integrated with the nut, there is no separate washer to handle during installation in applications where the flange provides the required bearing function. This can help simplify automated or high-volume assembly operations and reduce the possibility of losing or incorrectly installing separate washers. The six-sided nut body also provides straightforward wrench engagement for conventional tightening operations.
