Product Description

Electro - galvanized conical washers are mainly made of carbon steel as the base material, and then a layer of zinc is plated on the surface through an electroplating process. 

Material and Surface Treatment

Design Features

Application Scenarios

Electro - galvanized conical washers are mainly made of carbon steel as the base material, and then a layer of zinc is plated on the surface through an electroplating process. This zinc coating forms a protective barrier, which can effectively prevent the underlying carbon steel from rusting and corroding, thereby extending the service life of the washer. The electroplating process ensures that the zinc layer is evenly distributed on the surface of the washer, enhancing its anti - corrosion performance in general environments.

These washers have a conical structure, which is different from the flat shape of ordinary washers. The conical design allows them to exert a certain elastic force when tightened, helping to improve the stability of the bolted connection. Their dimensions, such as inner diameter, outer diameter and thickness, are usually designed according to relevant standards like GB/T 956.3 - 2017, ensuring good compatibility with matching bolts and nuts of corresponding specifications.

They are widely used in various mechanical equipment, electrical appliances, construction machinery and automotive parts. Due to the electro - galvanized surface treatment, they are suitable for use in dry or slightly humid indoor environments, such as in the assembly of household appliances, general industrial machinery and some non - corrosive outdoor equipment. However, they are not recommended for long - term use in highly corrosive environments like marine or chemical industries.

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.
