Product Description

Electro - galvanized anti - loosening washers are typically made of carbon steel as their base material. 

Material and Surface Treatment

Design Features

Application Scenarios

Electro - galvanized anti - loosening washers are typically made of carbon steel as their base material. Carbon steel offers good mechanical properties, providing the necessary strength and toughness for the washers to function effectively in various fastening applications. The electro - galvanizing process is then applied to the surface of the carbon steel. During electro - galvanizing, a layer of zinc is evenly deposited on the surface of the washer through an electrochemical reaction. This zinc coating not only gives the washer an attractive and corrosion - resistant finish but also acts as a sacrificial anode. In case of any minor damage to the surface, the zinc will corrode preferentially, protecting the underlying carbon steel from rusting and significantly extending the service life of the washer. This surface treatment is especially important in environments where moisture or mild corrosive substances are present.

These washers are designed with specific anti - loosening features. One common design is the use of teeth or serrations on the surface. For example, some anti - loosening washers have external teeth that bite into the mating surface when the bolt or nut is tightened. This increases the friction between the washer and the surface, preventing the relative movement that could lead to loosening. The shape of the washer, whether it is round, square, or has a more complex profile, is also carefully designed to optimize its anti - loosening performance. The inner diameter of the washer is precisely sized to fit the corresponding bolts or screws snugly, ensuring a proper fit and efficient transfer of the clamping force. Additionally, the thickness of the washer is determined based on the application requirements, with thicker washers often used in applications that require higher load - bearing capacity and more effective anti - loosening.

Electro - galvanized anti - loosening washers find wide applications in numerous industries. In the automotive industry, they are used in the assembly of engines, chassis components, and body structures. The vibrations and dynamic forces experienced by vehicles make the use of anti - loosening washers crucial to prevent the loosening of bolts and ensure the safety and performance of the vehicle. In the construction industry, they are employed in the erection of steel structures, bridges, and high - rise buildings. The large - scale and long - term nature of construction projects demands reliable fastening solutions, and anti - loosening washers meet this requirement by providing a secure connection that can withstand various environmental and mechanical stresses. In the manufacturing of industrial machinery, such as conveyor systems, power - generation equipment, and machine tools, anti - loosening washers are essential to keep the machinery running smoothly and prevent unexpected downtime due to loose connections. They are also used in the electronics industry for the assembly of delicate electronic devices where a secure and vibration - resistant connection is required.

Packing & Delivery

Bag Packaging

Carton Packaging

Fasteners can be packaged in durable plastic bags, which are available in various sizes to accommodate different quantities (e.g., small batches of screws, nuts, or bolts). The bags are typically sealed by heat or with a zipper to prevent moisture, dust, and loss of contents. This method is lightweight, cost-effective, and suitable for retail sales, small shipments, or situations where easy access to the fasteners is needed. Additionally, clear plastic bags allow for quick visual identification of the products inside.

For larger quantities or bulk transportation, cartons are commonly used. These are sturdy cardboard boxes, often reinforced with corrugated layers to provide protection against impact during handling and shipping. Fasteners in cartons are usually pre-packed in bags or separated by dividers to avoid friction and damage. Cartons can be labeled with product details (e.g., type, size, quantity) and are stackable, optimizing storage and logistics efficiency. This method is ideal for industrial orders, wholesale distribution, or long-distance transportation where durability is a priority.
