Flange Nuts

Flange nuts feature a wide integrated washer that helps distribute pressure across the mounting surface. These special nuts are often used in fastening applications with oversized holes too big for standard nuts. Flange nuts eliminate the need for washers, as the “flange” of the nut distributes pressure across a wider surface area.

Stainless Steel Serrated & Non-Serrated Flange Nuts at EPCO Sales

Because flange nuts have a wide surface area, they are often used in fastening applications that involve oversized or non-uniform holes. The protruding rim of the flange covers a greater surface area than a standard nut. Stainless steel flange nuts from EPCO provide a strong, versatile solution for convenient fastening.


Serrated vs. Non-Serrated Flange Nuts

Flange nuts are available in serrated or non-serrated styles. Serrated flange nuts feature edged serrations under the flange that cut into the mating surface when fastened, and keep the nut from loosening. Non-serrated flange nuts have a smooth underside, similar to a flat washer.
