Specification Brand : RAW PRODUCTS CORP BulletPoint1 : Zinc Plated Steel Serrated Flange Nuts BulletPoint2 : A 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. BulletPoint3 : Serrated for extra grip, note that this nut will scratch the surface it attaches to BulletPoint4 : Serrated flange nuts create a locking action, allowing a serrated flange nut to be substituted for a lock nut.
