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 double-stacked self-locking washer is a special mechanical connector designed to prevent bolts from loosening, especially in high-vibration or high-load environments.It consists of two spring washers nested inside each other in an S-shaped configuration. The outer spring washer has ends that bend inwards, while the inner spring washer has ends that bend outwards, creating a two-way self-locking feature.The working principle of this washer is based on elastic deformation. When placed between connecting parts, the inner curved part of the outer spring ring interlocks with the outer curved part of the inner spring ring, creating a locking force that prevents the connecting parts from loosening under vibration or load.The advantages of the double-stacked self-locking washer include high reliability, easy installation, and a wide range of applications.It is suitable for various mechanical connections, such as threaded connections and pin connections, and is widely used in industrial production and machinery manufacturing, especially in the automotive manufacturing process, where it is often used to connect engine and chassis systems to improve the safety and reliability of the car.
Hexagon nuts are used in conjunction with bolts and screws to connect and tighten mechanical components. Among them, 1 Hexagonal high-strength nuts are the most widely used, while C-grade high-strength nuts are used for machines with rough surfaces and low precision requirements
Metal Stamping parts products Building hardware stamping parts Can be made into different size according to customer’s requirements. Material: carbon steel, stainless steel,aluminum,copper,etc. Finish: white zinc plated, blue zinc plated, etc.
Twisted shear high-strength bolts are a special type of bolt with high strength and excellent torsional shear performance, widely used in engineering structures.

The window regulator motor is the power source of the window glass lifting system, responsible for driving the glass up and down. It is usually installed inside the car body or in the car door, connected to the window glass through steel wire ropes or guide rails, to achieve the control of the window lifting. The working principle of a motor is based on electromagnetic induction and changes in the direction of current. By changing the direction of current, the motor’s forward and reverse rotation can be controlled, thereby achieving the up or down movement of the car window. The start and stop of the motor are controlled by the switch inside the car, making it convenient for the driver to operate. In addition, in order to protect the motor, wire rope, and guide rail, a lubrication system is also installed in the system to provide lubricating oil for these components, reduce friction, and extend service life.
