Product Description

Electro - galvanized square nuts are a type of fastener.

Basic Definition: 

Main Materials: 

Application Scenarios:

As the name implies, "electro - galvanized" refers to the surface treatment process, which forms a thin zinc layer on the surface of the nuts by electroplating to enhance corrosion resistance. "Square nuts" indicate that their shape is square, with four sides and four corners, which are different from the common hexagonal nuts.

Usually made of carbon steel, and after electro - galvanizing treatment, they can have better rust - proof performance and appearance quality.

Widely used in various mechanical equipment, construction projects, electronic products and other fields. Because of their good corrosion resistance and certain fastening strength, they can play a role in connecting and fixing components.

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.
