Photovoltaic Support manufacturers Hebei Qierjie New Energy Technology Co.,Ltd, professional manufacturer for solar panel mount or called PV support bracket products, Flange Nut Galvanized, the main accessory for PV support bracket project during building solar system installation. Hex flange nut are used for pipe connections or parts which needed to increase the fitting surface with nut mostly.It鈥檚 one piece of washer and nut ,and there is the anti-slip tooth on the bottom,which increases the bonding between nut and the work-piece,compared to the ordinary nut and washer combination,it鈥檚 stronger and more tension. The flange nut is serrated at an Angle so that the nut does not rotate in the direction of the loose nut. They cannot be used with washers or on scratched surfaces due to serrations. The serration helps to prevent the vibration of the nut from moving the fastener, thus maintaining the retaining force of the nut. The flange nut has a wide flange at one end that acts as a one-piece washer. This is used to distribute the pressure of the nut over the part being secured, thus reducing the possibility of damage to the part and making it less likely to come loose due to uneven tightening surfaces. We Qierjie, professional manufacturer of solar mounting structures, can offer various solutions for different kinds of system, and manufacturing solar mounting structures, solar racking brackets, solar panel clamps and other structural components.
