Function mode of flange nut

Page view
Flange nuts, also known as cushioned nuts, Fang nuts, hexagonal flange nuts, flange nuts and so on. Most of them are used for pipe connections or workpieces requiring additional nut contact surfaces.
Flange nut material: A3 low carbon steel 35K high speed steel wire 45 # steel 40CR 35Crmoa
Hardness grade: 4 grade, 5 grade, 6 grade, 8 grade, 10 grade, 12 grade
Surface treatment: generally divided into color galvanized, white galvanized, black galvanized three kinds, and generally cold galvanized!
Main specifications: M5 M6 M8 M10 M12 M16 M20 (M20 and above specifications and M14 M18 flange nuts are not commonly used)
Flange nuts and general hexagonal nuts are basically the same size as thread specifications, but compared with hexagonal nuts, they are gaskets and nuts in one, and have anti-slip thread underneath, which increases the surface area contact between the nut and the workpiece. Compared with the combination of ordinary nuts and gaskets, they are more solid and have greater pulling force.
Generally common flange nut specifications are generally below M20, because most flange nuts are used in pipes and flanges, so subject to workpiece constraints, flange nut specifications are less than nuts. Most of the flange nuts above M20 are flat flanges, that is, there are no teeth on the flange surface. Most of these nuts are used in some special equipment and special places. Generally, there is no spot in the sales factory.
