High strength flat pad

Flat washer DIN125 Grade: 4.8, 8.8, 10.9, 12.9

Material: Q235, 35K, 45K, 40Cr, 35Crmo, 42Crmo, Surface Treatment: Blackened, Electrogalvanized, Dacromet, Hot-dip Galvanized, Galvanized, etc!

Flat pad is a type of gasket that is flat in shape.

Its main functions include: increasing the contact area, dispersing

pressure, and protecting the surface of the connected parts from scratches; Reduce the pressure damage of nut or bolt heads on the surface of the connected parts; Sometimes it can also play an auxiliary role in preventing loosening.

There are various materials for flat pads, including metal (such as carbon steel, stainless steel, etc.), plastic, rubber, etc. Its size and specifications vary depending on the usage scenario and the requirements of the connecting components.

Product Knowledge

Flat pad is a common mechanical component, usually a flat circular structure.

It plays an important role in mechanical connections:

Load dispersion: By increasing the contact area, the pressure applied by the nut or bolt is evenly distributed, reducing the damage caused by excessive local pressure to the connecting parts.
Surface protection: It prevents the heads of nuts and bolts from directly pressing against the surface of the connected parts, providing protection.
Auxiliary anti loosening: In some cases, it can be used in conjunction with spring washers to improve the anti loosening performance of the connection.

There are various types of materials for flat pads, including metals such as carbon steel, stainless steel, aluminum alloy, etc; Non metallic materials such as rubber, plastic, etc. Flat pads made of different materials have different characteristics and are suitable for different working environments and requirements.

Usage of bolt flat washer

1、 The function and characteristics of flat mats

Flat gasket, also known as flat gasket or flat gasket, is a type of gasket with the shape of a flat plate, commonly used as a gasket at the connection of fasteners. Its function is to disperse the tightening force of connectors, increase the contact area, and reduce loosening or fatigue damage caused by hydrophobicity, while effectively preventing water, gas, and oil leakage. The material of flat pads is generally metal or rubber, which has the characteristics of withstanding high temperature, high pressure, and wear resistance.

3、 Usage scenarios and precautions for products

Flat gaskets are usually used to connect fasteners such as impellers, pipes, elbows, flanges, etc. to ensure tightness and sealing between the connectors. When using, it is necessary to choose the appropriate material and thickness based on the pressure, temperature, and other parameters of the equipment to ensure its normal use.

4、When using, corresponding installation and usage requirements should be followed, and it should not be too tight or too loose to avoid mechanical damage or loosening, which may cause danger.

In summary, flat washers and washers are two commonly used gaskets in mechanical component connections, and their different shapes and sizes give them their unique usage scenarios and characteristics. When selecting and using, scientific and reasonable selection and use should be made based on the actual situation.

The common materials for flat washers are as follows:

Low carbon steel: It has good strength and toughness, relatively low cost, and is widely used in general mechanical connections.
Medium carbon steel: With high strength, it is suitable for situations where there are certain requirements for the strength of the gasket.
Stainless steel: It has good corrosion resistance and is commonly used as a connector for working in humid and corrosive environments.
Copper: It has good electrical and thermal conductivity and is commonly used in electrical connections or areas that require good thermal conductivity.
Aluminum: It is lightweight and has a certain strength, often used in situations where weight is required.
Nylon: It has good wear resistance, corrosion resistance, and insulation properties.
Rubber: It has good elasticity and can play a role in shock absorption, sealing, and anti loosening.
Polytetrafluoroethylene (PTFE): It has an extremely low coefficient of friction and good corrosion resistance, making it suitable for special working conditions.
