Product Description

Hot - Dip Galvanized Square Nuts are a type of fastener. 

Appearance and Structure:

Manufacturing Process: 

Application Fields:

 They are four - sided nuts, usually matched with square - headed bolts. Compared with standard hex nuts, they have a larger contact area with the fastened parts, which provides better resistance to loosening. However, this also leads to greater resistance during tightening, making them a bit more difficult to install firmly. Square nuts up to # 10 are flat on both sides, and those with a size of 1/4" and above are beveled on one side.

Hot - dip galvanized square nuts are manufactured by submerging square nuts in molten zinc at about 500ºC. Through this process, a zinc layer is adhered to the surface of the nuts, which plays a role in anti - corrosion.

They are widely used in various fields. In the power line hardware system, they can be equipped with anchor rods to meet the needs of power and public facilities. They are also commonly used in the construction industry, mechanical manufacturing, automotive manufacturing and other fields, playing the role of 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.
