Product Description

Hot - dip galvanized hexagon socket head cap screws are widely used high - quality fasteners. 

Performance Characteristics: 

Common Specifications

Application Fields:

The zinc coating of hot - dip galvanized hexagon socket head cap screws can effectively isolate the contact between the base metal and the outside world, preventing corrosion. According to the standard, the zinc layer thickness of M8 - M12 is usually 40 - 50 microns, and that of M20 and above is 60 - 80 microns. In addition, the hot - dip galvanizing process has high coating uniformity, and the thickness deviation is within ±10%, which can ensure the service life of the screw in different environments.

The specifications are diverse, and the common thread diameters range from M3 to M64, and the lengths range from 5mm to 300mm or even longer. The strength grades include 4.8 - grade, 8.8 - grade, 10.9 - grade, etc., which can meet the connection needs of different projects.

They are widely used in construction, infrastructure, machinery manufacturing, automotive industry and other fields. For example, in construction projects, they are used for the connection of steel structures; in the machinery manufacturing industry, they are used for the assembly of various mechanical equipment, which can ensure the firmness and stability of the connection, and can also maintain good performance in harsh environments.

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.
