Product Description

Electro - galvanized hexagon bolts are a common type of mechanical fasteners.

Basic Structure: 

Surface Treatment:

Application Scenarios:

The head is hexagonal, which is convenient for tightening or disassembling with tools such as wrenches or sockets. The screw part is provided with external threads, which can be used in conjunction with nuts to fix two or more components together through threaded connections.

The surface is treated by electro - galvanizing, that is, a layer of zinc is coated on the surface of the bolt through electroplating. This treatment can provide basic anti - corrosion protection.
Features: Compared with hot - dip galvanized bolts, the zinc layer of electro - galvanized hexagon bolts is thinner, and the corrosion resistance is relatively weaker, but it is suitable for mild outdoor and indoor environments. It has the characteristics of easy installation, and can provide a firm and stable connection, helping to resist movement.

Widely used in various industries, such as in the electrical installation industry, it is used to fix circuit boards, shells, etc.; in furniture assembly, it is used for the splicing of tables, chairs, wardrobes, etc.; it can also be used in some light - duty projects, playing the role of 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.
