Why use combination screws with washing machines instead of ordinary screws in some products?

Stability brought by structural design
Combination screws with washers are usually made up of a combination of screw bodies and a matching washer, which enhances the stability of the fastening connection. Compared with ordinary screws, combined screws can disperse pressure more evenly when connected, reducing local stress concentration, thereby reducing the possibility of loosening and damage. Especially in environments with more vibrations, this combined structure can effectively resist loosening caused by vibration, ensuring long-term stability of the connector.

Improved anti-loosening performance
During use, ordinary screws are prone to loosening due to external vibration or thermal expansion and contraction. The combination screws with washers increase friction through specially designed washer, which helps to lock the locking effect. The reasonable combination of the washer material and shape allows it to maintain a certain pretension force after tightening, prevent the screw from loosening during operation, and ensure the safe operation of mechanical equipment or products.

Installation efficiency and convenience
combination screws with washers integrate fasteners and washers, reducing the need to match washers separately during assembly and simplifying the installation process. This not only saves time, but also reduces the probability of operational errors. On the production line, this combination screw helps improve assembly efficiency and is suitable for the needs of rapid installation in large quantities. Compared with ordinary screws and independent washer, combined screws are easier to operate in standard and improve production consistency.

Material adaptability and durability
Combination screws with washers generally use specially treated metal materials, which have good corrosion resistance and mechanical strength. This material selection ensures the service life of the screw in different environments, especially in situations where there are many wet or chemical media, the combined screw can still maintain a stable connection. If ordinary screws do not have additional protection, they will easily rust or damage, affecting the safety of the overall structure.

Diverse application scenarios
The design of some products puts higher requirements on fasteners, such as household appliances, mechanical equipment, automotive parts and other fields. combination screws with washers are suitable for these devices that require long-term and stable operation due to their loose and durable properties. Compared with ordinary screws, it can better cope with complex working conditions, reduce maintenance frequency and repair costs, and improve the overall user experience.

Economic benefits and comprehensive considerations
Although the cost of combining screws with washers may be slightly higher than that of ordinary screws, its advantages in installation efficiency, anti-loosening effect and service life can reduce the risk of failure and maintenance costs caused by loose screws. In the long run, this combination screw helps the company save expenses for subsequent maintenance and replacement, reflecting a high comprehensive value.

Choosing combination screws with washers instead of ordinary screws is mainly to improve the reliability and durability of the fastening connection. Its structural design, anti-loosening ability, installation ease and material properties make it suitable for use in products with high requirements for connection stability. Through reasonable selection and use, it can provide effective guarantees for the safety and service life of the product.
