Flat Filling Washer Industry Knowledge Extension

The main purpose of Flat Filling Washers

The Flat Filling Washer is mainly used to reduce pressure. When some parts are tightened with a large axial force, the washer is easy to be pressed into a dish shape. At this time, it can be solved by changing the material and increasing the hardness.

The locking effect of the spring washer is average, the important parts are used less or not as much as possible, and the self-locking structure is adopted. For spring washers used for high-speed tightening (pneumatic or electric), it is best to use surface phosphating-treated washers to improve their anti-friction performance, otherwise, they are prone to friction and heat and burn out or open, or even damage the surface of the connected parts. For thin plate joints, spring washer construction should not be used. According to statistics, spring washers are used less and less in automobiles.

Due to the large and uniform locking force, the connecting tooth shape in the toothed elastic washer is used more in the automotive industry, while the spaced tooth shape is less.

Common materials for Flat Filling Washers

Flat Filling Washers can be made from a variety of materials, including:

Steel: The most common material, strong and durable, used in construction and industrial applications.

Stainless Steel: Corrosion resistant, suitable for outdoor and harsh environments.

Brass: Good electrical conductivity, used in electrical applications.

Aluminum: Lightweight and corrosion resistant, used in marine and aerospace applications.

Plastic: Lightweight, non-conductive, used in electrical and non-critical mechanical applications.

Fiber: Strong and lightweight for use in high temperature and corrosive environments.

Material selection depends on the specific application and required strength, corrosion resistance, and other factors such as temperature and weight.

Use of Flat Filling Washers

Flat Filling Washers are typically used for:

Balance the pressure between the bolt or screw head and the object to prevent the bolt or screw head from scratching the surface of the object.

Increase the contact area between the bolt or screw head and the object to increase the fastening effect.

Reduces unbalance in bolt or screw heads due to over tightened or loose nuts.

In electrical and electronic applications as insulation to prevent short circuits.

Flat Filling Washers are commonly used for fastening and mounting various objects such as mechanical equipment, furniture, electrical equipment, etc. The fastening effect depends on the size of the bolt or screw used, the weight of the object and the material of the Flat Filling Washer.
