Our Industrial Hex Flange Nuts combine the familiar wrenching geometry of a hex nut with an integrated flange that provides a larger bearing surface beneath the nut. This integrated design allows clamping forces to be distributed over a broader contact area, helping create a more stable connection between the nut and the mating component. In suitable applications, the flange can also eliminate the need for a separate washer, reducing the number of loose components involved in assembly and helping streamline production. Designed for industrial machinery, OEM equipment, automotive components, metal fabrication, electrical equipment, and general mechanical assemblies, these flange nuts provide a practical balance of fastening efficiency, standardized compatibility, and application flexibility.
The defining advantage of an Industrial Hex Flange Nut is the built-in bearing flange. Unlike a conventional hex nut that concentrates its contact around the relatively small nut bearing surface, the integrated flange extends the contact area beneath the nut. This helps distribute tightening pressure more evenly across the mating surface and can reduce localized contact stress in suitable assemblies. The larger bearing surface is particularly useful when fastening sheet metal, brackets, panels, machine components, and other parts where stable load distribution is important. It also provides a convenient alternative to a separate nut-and-washer combination when the application and joint design allow it.
Our Industrial Hex Flange Nuts are available in 1010 and 1035 carbon steel, as well as Brass, giving buyers multiple material options for different industrial requirements. Carbon steel provides a practical combination of strength, machinability, durability, and cost efficiency for general mechanical fastening. The available steel mechanical property classes include ISO 898-2 Class 6 and Class 8 for metric applications and SAE J995 Grade 2 and Grade 5 for inch-based applications. Brass provides a non-ferrous alternative for applications where properties such as corrosion resistance, electrical conductivity, appearance, or reduced magnetic response are desirable. Brass products should be selected according to their specific material properties and actual application requirements rather than applying carbon-steel strength classifications directly to them.
Our Industrial Hex Flange Nuts are manufactured according to internationally recognized standards, including DIN 6923, ASME B18.2.2, and ASME B18.16.4. These standards provide established dimensional requirements for metric and inch fastening systems, helping ensure compatibility with corresponding bolts and threaded components.

In suitable applications, the integrated flange can perform a bearing function that would otherwise require a separate washer. This can provide a practical advantage in high-volume manufacturing and production-line assembly, where reducing the number of individual components can simplify handling and improve assembly efficiency. Fewer loose components can also make automated or semi-automated assembly easier to manage. However, the flange should not automatically be considered a replacement for every washer application; joint load, surface condition, hole geometry, and engineering requirements should be evaluated when specifying the fastening system.
Industrial Hex Flange Nuts are available in Black, Zinc Plated (ZP), and Hot-Dip Galvanized (HDG) finishes for different environmental and corrosion protection requirements.
A practical solution for general industrial applications and assemblies where a dark surface is preferred.
Enhanced corrosion protection for common indoor and moderately corrosive environments.
A more substantial zinc protective coating for outdoor equipment, construction, and moisture-exposed environments.
The combination of a robust hexagonal body and integrated flange makes these nuts particularly useful across a wide range of industrial applications. Typical uses include machinery manufacturing, automotive components, industrial equipment, metal structures, sheet metal assemblies, electrical equipment, brackets, frames, and OEM products. In production environments, the flange can provide a more stable bearing interface while the standard hex body allows installation with conventional tools. This combination makes the product easy to incorporate into established fastening processes without requiring a completely different installation method.
For industrial buyers, selecting the right fastening component is not simply about nominal thread size. Factors such as bearing area, assembly efficiency, material, mechanical grade, corrosion protection, dimensional standard, and compatibility with existing bolts all influence the overall value of the product. Industrial Hex Flange Nuts bring these considerations together in a standardized component, allowing buyers to specify the required material, strength class, size, and finish according to the application. For OEMs and distributors purchasing in volume, the standardized product family can also simplify procurement and reduce the need to manage separate nut and washer components where the flange design is appropriate.
With 1010 and 1035 carbon steel, Brass material options, DIN 6923 and ASME dimensional standards, ISO 898-2 Class 6/8 and SAE J995 Grade 2/5 options for applicable steel products, M3–M16 and 1/4"–5/8" sizes, and Black/ZP/HDG finishes, our Industrial Hex Flange Nuts provide a flexible solution for manufacturers, distributors, automotive suppliers, machinery producers, and industrial procurement teams.
Their combination of integrated bearing flange, standardized dimensions, broad material selection, multiple strength grades, and flexible surface finishes makes them a practical choice for applications where reliable fastening and efficient assembly are equally important — a straightforward way to combine secure threaded engagement with an integrated bearing function in a single component.
