Product Description

Hot - dip galvanized flange nuts, also known as hexagon nuts with flange, are a type of fastener. 

Definition and Manufacturing Process:

Design Features: 

Application Scenarios: 

 Hot - dip galvanized flange nuts are produced through a strict hot - dip galvanizing process. The nuts are usually made of carbon steel and are dipped into a molten zinc bath at about 450°C. As a result, a firm and corrosion - resistant zinc coating is formed on their surface, which can provide excellent protection against rust and harsh environmental conditions.

These nuts have internal threads that match the external threads of bolts. They are characterized by an enlarged circular base, which increases the bearing surface area. The wide flange is equivalent to an integrated non - rotating washer, which can evenly distribute the load and enhance the firmness of the connection. Some flange nuts also have serrations on the bottom, which can play a anti - loosening role and increase the holding force by preventing vibration.

They are widely used in construction, infrastructure development, marine engineering, outdoor installations and other fields. Whenever a sturdy and corrosion - resistant fastening solution is required, hot - dip galvanized flange nuts can play an important role.

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.
