Hex Flange Nut
Product Overview
Our hex flange nuts are designed with a hexagonal body and an integrated flange at the base. The flange increases the bearing surface area, distributing pressure more evenly and helping to prevent damage to the mating surface. In many applications, the flange design can eliminate the need for a separate washer.
Available with a serrated flange for added locking power and vibration resistance, or a smooth flange for general fastening and surface protection. Ideal for automotive, machinery, construction, electrical, and industrial assembly.
Also known as: Flange Nut, Serrated Flange Nut, Smooth Flange Nut, Hex Washer Nut, Spinlock Nut.
