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.

Flange Nut Uses
Due to the small size of flange nuts, irregular shapes, and some need to be threaded, there are some obvious defects in hot-dip galvanizing.

1. The thread is difficult to screw after plating. After hot-dip galvanizing, the residual zinc sticking to the thread is not easy to remove, and the thickness of the zinc layer is not uniform, which affects the cooperation of the threaded parts.

2. The high operating temperature of hot-dip galvanizing will reduce the mechanical strength of the high-strength flange nut. The strength of some threads of 8.8 bolts after hot dip galvanizing will be lower than the standard requirements.

3. The hot-dip galvanizing process of fasteners is carried out at high temperatures. When the solvent is dried and the workpiece to be plated is dipped into the pool, strong and irritating hydrogen gas will be precipitated.

Although there are many defects in hot-dip galvanizing of fasteners, because of the thick coating, good bonding strength and long-term corrosion effect of hot-dip galvanized fasteners. It has always been respected in the power, communications, and transportation sectors.

Surface Treatment: The surface treatment of the hexagonal flange nuts can be generally divided into three types - color galvanized, white galvanized, black galvanized, and generally cold galvanized!

Main Flanged Nut Specifications: M5 M6 M8 M10 M12 M16 M20 (M20 and above specifications and M14 M18 flange nuts are not commonly used)

Related functions of flange nuts and general hexagon nuts are basically the same size and thread specification, but compared with hex nuts for sale, it is a one-piece gasket and nut, and there are anti-slip tooth patterns on the bottom, which increases the size of the nut and the workpiece. Compared with the combination of ordinary nut and washer, it is firmer and has greater tensile force. Generally, the specifications of common flange nuts are generally below M20. Because most flanged nuts are used on pipes and flanges, they are restricted by the workpiece, and the specifications of flange nuts are smaller than those of nuts. Some flanged nuts above M20 are mostly flat flanges, that is, there is no tooth pattern on the flange surface. Most of these wholesale fasteners are used in some special equipment and special places.
