Flange nuts

Flange nuts, with nuts, flower nuts, hexagonal flange nuts, flange nuts, etc., are mostly used in pipe connections or need to increase the nut contact surface of the workpiece. Function or use: mostly used in the pipeline connection or need to increase the nut contact surface of the workpiece

flange nuts

Flange nuts and general hex nuts are basically the same size as threaded sizes, except that they are integral with hex nuts and nuts are non-slip, which increases the nut and the workpiece Of the surface area of contact, compared to ordinary nut plus gasket combination, more solid and more force. [1]
Commonly common flange nut specifications are generally below the M20, because most of the flange nuts are used in the pipeline and the flange, so subject to the workpiece, flange nut specifications compared with the nut is less. M20 above some of the flange nuts are mostly flat flange, is the flange surface without teeth, most of these nuts used in some special equipment and special places.
