Our flange nuts feature an integrated flange at the bottom of the nut, creating a larger bearing surface between the fastener and the connected component. Compared with standard nuts, this integrated design helps distribute clamping pressure over a wider area, reducing localized stress and minimizing the risk of surface deformation or damage during tightening. The flange can also improve joint stability and, in many applications, reduce or eliminate the need for a separate washer, helping simplify assembly and reduce the number of individual components.
Available in carbon steel, stainless steel, alloy steel, and other materials, flange nuts can be supplied with different thread standards, sizes, strength grades, and surface finishes. Serrated flange versions can additionally provide enhanced resistance to loosening by increasing friction between the nut and mating surface. These products are widely used in automotive manufacturing, machinery, sheet metal assemblies, electrical equipment, industrial structures, agricultural machinery, and other applications where reliable clamping and effective load distribution are required. OEM and customized flange dimensions are also available for special assembly requirements.
