Product Description

Product Description

1. Basic Concepts

Flat washers, also known as flat washers, are thin pieces stamped out of iron plates or other materials, usually with a central hole for placing fasteners such as bolts and screws. Its main function is to disperse the pressure of the fastener on the connected parts, protect the surface of the connected parts, and prevent loosening and air leakage.

2. Main functions and uses

Dispersing pressure: Flat washers can increase the contact area, thereby reducing the pressure per unit area of the fastener on the connected parts and preventing damage to the surface of the connected parts.
Protecting the surface: By providing an additional layer of material, flat washers can prevent direct contact between fasteners and connected parts, reducing friction and wear.
Preventing loosening: Although flat washers themselves do not provide elastic deformation, when used in conjunction with fasteners, they can increase the stability of the connection and prevent loosening.
Isolation and sealing: In some cases, flat washers can also play the role of isolation and sealing to prevent liquid or gas leakage.

3. Materials and manufacturing processes

Materials: Flat washers are made of a variety of materials, including metal materials such as stainless steel, copper, aluminum, titanium, and non-metallic materials such as rubber and plastic. When selecting materials, it is necessary to consider factors such as the specific use environment, corrosion resistance and strength requirements.
Manufacturing process: Flat washers are usually manufactured through a stamping process, which has the advantages of low cost and high production efficiency.
