Comprehensive Introduction to Common Nails

I. Product Overview
Common nails, also referred to as iron nails or round nails, are fundamental hardware components widely utilized in construction, renovation, and furniture - making. Their primary function is to connect and secure materials such as wood, plastic, and metal. Usually crafted from low - carbon steel, common nails come at a low cost and are available in a wide range of models, making them suitable for various scenarios.

II. Key Features
Material Composition
Common nails are typically made from low - carbon steel grades like Q195, Q215, or Q235. These steel types offer excellent toughness, facilitating easy processing while maintaining a certain level of strength.
Specification Details
Length: They are commonly available in lengths ranging from 1 inch to 6 inches, which is equivalent to 25mm to 150mm.
Diameter: Depending on the intended use, there are heavy - duty, standard, and light - duty diameters. The heavy - duty diameter is approximately 2.5mm, the standard is around 2.2mm, and the light - duty is about 2.0mm.
Model Example: Take the 40# round nail as an example. It has a length of 40mm, and the heavy - duty 40# round nail has a diameter of 2.5mm.
Surface Treatments
Polished: Polished common nails have a smooth surface but relatively poor corrosion resistance, making them suitable for use in dry environments.
Galvanized: Galvanized nails have strong rust - proof properties and can withstand humid conditions, such as in outdoor settings or bathrooms.
Performance Characteristics
High Flexibility: Common nails can be bent by more than 90° without breaking easily.
Corrosion and Rust Resistance: The galvanized layer or the polishing process provides the nails with a certain degree of oxidation resistance.

III. Manufacturing Process
The manufacturing of common nails begins with cold - drawing high - quality wire rods into steel wires. Then, a nail - making machine is used to shape the steel wires into nails with flat heads, round shanks, and diamond - shaped tips. Finally, surface treatments like polishing or galvanization are applied.

IV. Packaging Options
Common nails are mainly packaged in the following ways:


Boxed: Each box contains 5 kg, and each carton holds 25 boxes.
Carton - Packed: A carton can hold 25 kg of loose common nails.
Customized Packaging: wooden box or other special packaging methods can also be arranged according to the specific requirements of customers.

V. Application Scenarios
Construction: In the construction industry, common nails are used to fix templates, build scaffolding, and install wooden keels.
Decoration: They can be used to fix gypsum boards, floors, skirting boards, and also for assembling furniture.
Packaging: In the packaging sector, common nails are mainly used for binding wooden boxes.
Daily Maintenance: At home, common nails are used for tasks such as hanging pictures and reinforcing wooden furniture.

VI. Purchase Considerations
Appearance Check: Select nails with intact heads and straight shanks, avoiding those that are bent or rusty.
Surface Inspection: The galvanized layer should be uniform without any missing areas, and the surface of polished nails should be smooth without burrs.
Weight Assessment: For nails of the same specification, heavier ones usually have thicker materials and better quality.
Model Selection: Choose the appropriate length and diameter according to the actual usage requirements. For example, light - duty nails can be used for fixing thin plates, while heavy - duty nails are required for load - bearing structures.

VII. Precautions
Usage Limitations: Common nails are not suitable for direct use in concrete or brick walls. In such cases, cement steel nails should be used instead.
Rust Prevention: If the nails are to be used in a humid environment, it is advisable to choose galvanized nails or apply paint to the surface after nailing.
Safety Operation: When using common nails, be careful to avoid nail injuries. For hard materials, it is best to drill a hole first before nailing.

VIII. Pricing and Supply
The price of common nails varies depending on the specification and surface treatment, generally ranging from 4,000 to 5,000 yuan per ton. They are widely available, not only meeting the domestic market demand but also being exported to many countries such as those in Europe, America, and the Middle East.

​IX. Additional Information
There are also some derivative types of common nails, such as roofing nails for fixing tile roofs and special - purpose nails like headless nails and powder - actuated nails. Users can choose the appropriate type of nail according to the specific application scenario.
