The proportion of wholesale flanged nuts production of DATIAN (DT) Fasteners is increasing year by year. Compared with the normal hexagon nuts, the flange nut has one more circular flange with a tooth pattern, which is firmer and has the effect of preventing loosening. The hexagon flange nut is mostly used in pipeline connections or workplaces that need to increase the contact surface of the nut.

EN 1661/14218 hex flange nut is a nut with a wide flange at one end that acts as an integral washer. This serves to distribute the pressure of the nut over the part being fastened, reducing the possibility of damage to the part and making it less likely to loosen due to uneven tightening surfaces. These large flange nuts are mostly hexagonal in shape and are made of hardened steel, usually plated with zinc.
