Definition:
Generally, nuts with hexagonal flange faces are called flange nuts. The use of flange nuts is also very common. Generally, many screws and bolts require the use of flange nuts. And if flange nuts are used, the fastening is very good. There is a flange that fits well with screws and bolts. The fastening performance is much better than that of hexagonal nuts.
The basic knowledge of flange nuts is introduced as follows: flange nuts come in both iron and stainless steel. But iron is more commonly used. And it can also be electroplated according to the color required by the customer. Generally, electroplating treatment has both environmentally friendly and non environmentally friendly options. Electroplating includes environmentally friendly colored zinc, environmentally friendly nickel, environmentally friendly blue zinc, environmentally friendly black zinc, etc., as well as ordinary electroplating, white zinc, colored zinc, black zinc, white nickel, etc.
English name for flange nuts: Hexagon nuts with flange;
Other names for flange nuts: gasket nut, serrated nut, hexagonal flange nut, flange nut, etc;
The function or use of flange nuts: mostly used in pipeline connections or workpieces that require increasing the contact surface of nuts;
Flange nut material: A3 low carbon steel 35K high-speed steel wire 45 # steel 40CR 35CrMoa;
Hardness level of flange nut: 4 levels, 5 levels, 6 levels, 8 levels, 10 levels, and 12 levels;
Surface treatment of flange nuts: generally divided into two types: color zinc plating and white zinc plating, and generally cold galvanizing;
Main specifications of flange nuts: M5 M6 M8 M10 M12 M16 M20 (flange nuts with M20 and above specifications and M14 M18 are not commonly used);
Flange nut thread specification: Refer to the national standard nut thread;
National standard code for flange nuts: GB6177-2000;
Usage characteristics:
1.Piping: Use a pipe cutter or grinding wheel cutting machine (with dedicated cutting blades) to vertically cut stainless steel pipes to the required length, remove burrs from the ends, and round them;
2.Welding: The left and right conical flange plates (with grooves, specially designed for embedding double-sided flange gaskets) are welded to the two pipe ports that need to be connected using tungsten inert gas welding (TIG welding);
3.Gasket: A double-sided flange sealing gasket is lined between the left and right flange plates;
4.Tightening: Clamp the two flange plates with clamps, and then use fastening screws (hexagon socket bolts) to clamp the flange or tighten the handle (one end of the external thread is connected to the internal thread of the handle, and the other end is connected with a fixed rivet for flexible connection)

A hinge is a mechanical device used to connect two solids and allow for relative rotation between them. It is usually composed of movable components or foldable materials. The main function of the hinge is to assist in the opening and closing of the cabinet, by connecting the rotating pair, so that the door or cover can swing on the fixed frame. According to different installation positions, hinges can be divided into door hinges and cabinet hinges. Door hinges are used to allow doors to rotate naturally and smoothly to open and close, while cabinet hinges have more functions and designs, such as rotating 360 degrees, adjusting the gap between doors up, down, and left and right.
