Hex Flange Nuts is a nut that has a wide flange at one end which acts as an integrated washer that does not move or spin. The serrated flange distributes the pressure of the nut over the part being secured and creates a locking action to prevent loosening.Flanged nuts spread their fastening force over a wider area than traditional nuts. This reduces the potential for damage to the mounting surface and allows for a more secure connection on uneven mounting surfaces.Hex Nut with Extended Flange Bearing Surface -- Many Available with Underside Serrations for Additional Locking / Holding Strength.

Hex Flange Nuts are hex nuts with a wide flanged portion near one end that acts as an integrated non-spinning washer. Flange nuts are used to spread the load placed on the nut over a wider surface area to prevent damage to the installation material. The flange acts as a washer, which allows the nut to fasten evenly to the installation material's surface.
Hex flange nuts are very common and used widely in softer installation materials. These nuts come with a serrated flange. These flange nuts come with serrations on the flange's bottom to create a locking effect. The serrations bite into the material installed, making the nut less likely to loosen over time due to vibrations. Hex flange nuts also save time and money by removing the need for a washer added to each fastener assembly during installation.
Flange wing nuts, or washer base wing nuts, are variations of traditional wing nuts. These wing nuts feature an additional integrated smooth washer, effectively combining a flat washer with a wing nut. The flange portion helps to distribute pressure from the fastener assembly over a wider surface area. This allows for an even more straightforward installation and removal by removing the need for a washer.
18-8 or 304 grades of Stainless steel are suitable for many general purpose applications, especially freshwater and non-salt water wet environments. Corrosion-resistant and durable, 18-8 stainless steel is equivalent to the A2 grade of stainless steel.
Zinc is by far the most common and economical type of plating for fasteners. The zinc plating adds a protective "sacrificial" top layer against corrosion while also adding a shiny finish to the fastener. Zinc plating is ideal for indoor use where it won't be constantly exposed to harsh elements.
