Flange nuts are a category in Qingdao's non-standard nut products. The head of this type of nut has a gasket-style nut, so it is also called: flange nut, tooth nut, nut with pad, and hexagonal flange Face nuts, etc., are mostly used in pipe connections or workpieces that need to increase the nut contact surface.

Function performance: The size of flange nut and general hex nut is basically the same as the thread specification, but compared with hex nut, it is a one-piece gasket and nut, and there are anti-skid teeth underneath, which increases The nut is in contact with the surface area of the workpiece, which is stronger and stronger than the combination of ordinary nuts and washers.

Specification introduction: Generally, the specifications of common flange nuts are generally below M20. Because most of them are used on pipes and flanges, they are restricted by the workpiece, and the specifications of flange nuts are less than that of nuts. Most of the flanges above M20 are flat flanges, that is, there is no tooth pattern on the flange surface. Most of these nuts are used in some special equipment and special places.
