SCREW WASHERS Factory

Screw washers are an indispensable part of hardware accessories. Their main function is to provide the necessary support and spacing between the screw and the connection surface. Screw washers play a vital role in mechanical engineering, construction projects and car repairs. They can disperse the pressure of the screw on the connection surface, avoid damage caused by stress concentration, and effectively prevent the screw from loosening, ensuring the stability and safety of the connection. There are many types of screw washers, such as flat washers, spring washers and locking washers, each of which has its specific uses and advantages. When selecting and using, it is necessary to select the appropriate washers based on factors such as the material, hardness and surface condition of the connection surface, as well as the specifications and size of the screws. This ensures that the washers can provide sufficient support and protection, while avoiding problems such as improper installation or poor fastening. Therefore, screw washers are one of the key accessories to ensure the effectiveness of screw connections.

What is the load dispersing function of the products under the screw washers category?

Yuyao Cili Machinery Co., Ltd. is a manufacturer specializing in the design and production of self-drilling screws, wood screws and window expansion screws. Our factory covers an area of ​​15,000 square meters and has more than 200 professional employees. We are equipped with advanced production equipment, including wire drawing, annealing cold punching, clamping and rolling equipment, and have a skilled team and a strict quality inspection system to ensure that we provide customers with high-quality products and services. With years of accumulated experience, we can customize production according to samples or drawings provided by customers to meet various needs. In modern fastener technology, Screw Washers, as an important component, play a vital role. One of their main functions in screw connections is load dispersing, which is of great significance to improving the reliability of connections and extending service life. The following will introduce in detail the load dispersing function of screw washers and their advantages in different applications.

1. Basic functions of screw washers
Screw washers are usually located between nuts and connected materials to provide uniform support and load dispersing. Its main functions are as follows.
Distribute pressure: By increasing the contact area, screw washers can distribute the pressure applied by the bolt or nut to a larger area, thereby reducing the local pressure on the connected materials. This can effectively prevent the material from being dented or deformed.
Protect the surface: Screw washers can prevent the screw head or nut from making direct contact with the surface of the connected material, thereby protecting the surface from wear and scratches.
Enhance stability: By providing additional support, screw washers can improve the stability of the connection and reduce the risk of loosening due to vibration or impact.

2. Load distribution mechanism
Screw washers achieve load distribution through the following mechanisms.
Increase contact area: Flat washers increase the contact area through their larger diameter. This design can distribute the load applied to the screw to a larger area, reduce local stress concentration, and thus protect the connected materials.
Distribute the load evenly: Spring washers and lock washers have elastic or special shape designs that can provide continuous pressure after the screw is tightened, further distributing the load evenly and avoiding material damage caused by excessive local pressure.
Relieve stress concentration: By providing a smooth surface and uniform pressure distribution, screw washers can effectively relieve stress concentration between the screw head and the connected material, and reduce the impact of material stress concentration on the connection strength.

3. Load dispersing characteristics of different types of screw washers
Depending on different application requirements, there are many types of screw washers, each with its own unique load dispersing characteristics.
The round design of the flat washer enables it to evenly disperse the load of the bolt or nut, and is particularly suitable for connections that require large-area support. For example, in the connection of wood and metal materials, flat washers can effectively disperse the load and prevent local deformation and depression of the material.
The elastic properties of spring washers enable them to provide continuous pressure and are suitable for applications with vibration or dynamic loads. They can maintain a certain preload after the screw is tightened, thereby improving the stability and reliability of the connection.
Lock washers increase friction through their special shapes, such as gears or waves, to prevent nuts from loosening due to vibration or external forces. While dispersing the load, they also provide an additional locking effect, enhancing the safety of the connection.
The larger outer diameter design of the self-washer enables it to provide a larger contact area, thereby dispersing the load and protecting the connection materials. This design is particularly suitable for applications that require large-area support, such as large machinery and building structures.

4. Advantages of screw washers in different applications
Construction and decoration: In the field of construction and decoration, screw washers are used in the connection of wood, metal and concrete to protect the material surface by dispersing the load and prevent material damage or deformation due to the pressure applied by the fasteners.
Automobile and machinery: In the field of automobile and machinery, screw washers can effectively disperse the load caused by vibration and impact, and improve the stability and safety of the connection. Spring washers and lock washers are particularly important in these applications because they can provide additional locking effect and load dispersing ability.
Home appliances and electronic products: In home appliances and electronic products, screw washers are not only used to disperse the load, but also to prevent damage to the material due to overheating or current leakage. Insulating washers play a key role in these applications.

5. The influence of material selection on load dispersal
The material selection of screw washers has an important influence on their load dispersing performance. Common materials include.
Carbon steel: Carbon steel screw washers have high strength and are suitable for general load dispersal. Carbon steel washers with zinc plating can improve corrosion resistance and are suitable for various environments.
Stainless steel: Stainless steel screw washers have excellent corrosion resistance and are suitable for load distribution in harsh environments, such as chemicals and humid environments.
Aluminum alloy: Aluminum alloy screw washers are lightweight and corrosion-resistant, suitable for light applications and occasions where weight reduction is required.
Nylon and plastic: Nylon and plastic screw washers are used for electrical insulation and light applications, and can provide good load distribution and chemical corrosion resistance.
