What are the differences between flange nuts and hexagon nuts

The size of flange nut and general hex nut is basically the same as the thread specification, but compared to hex nut, it is a one-piece gasket and nut, and there are anti-skid teeth underneath, which enlarges the nut and the workpiece Compared with the combination of ordinary nut and washer, it is stronger and more tensile.

Generally, the specifications of common flange nuts are generally below M20. Because most flange nuts are used on pipes and flanges, they are restricted by the workpiece, and the specifications of flange nuts are less than that of nuts. Some flange nuts above M20 are mostly 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, and the general sales manufacturers do not have the spot.
