Serrated Hex Flange Nuts
Hex Nuts with an Integral Washer
A Hex Flange Nut is a nut that has a wide flange at one end that acts as an integrated, non-spinning washer. This serves to distribute the pressure of the nut over the part being secured, reducing the chance of damage to the part and making it less likely to loosen as a result of an uneven fastening surface. Serrated flange nuts create a locking action, allowing a serrated flange nut to be substituted for a lock nut. Flange nuts are available in Stainless Steel and Zinc Plated Steel for corrosion resistance.
