Copper Nails: Types, Uses, and Common Sizes of Copper Nails

In modern manufacturing, copper nails, as a small and important component, play a crucial role in various application fields. They are not just simple metal components, but also key components of many products and structures.

Whether in the field of construction, mechanical manufacturing, or electronic equipment assembly, copper nails stand out for their conductivity, corrosion resistance, and stability.

This article will delve into the types, uses, and common sizes of copper nails, revealing the outstanding value of these small metal objects in the manufacturing field.

Overview of copper nails: What is copper nails?

Copper nails are small fixing devices made of copper, typically used to connect, secure, or support different components. Its structure is nail shaped (usually including a nail head and a slender nail pillar).

The shape and size of copper nails can vary depending on their specific use, and they can be various types such as straight nails, threaded nails, screws, etc. Each type has a specific purpose.

During the assembly process, copper nails are usually firmly connected to various materials by striking or pressing, ensuring the reliability of the connecting components.

Different types of copper nails

Copper nails come in various types, and their design and shape vary depending on specific applications and needs. The following are some common types of copper nails:

1.Solid copper nails

Straight nails are the most basic type of copper nails, usually cylindrical in shape without threads, and their length and diameter may vary depending on specific usage and requirements. Commonly used in assembling mechanical components, electronic devices, and other manufactured products.

This type of copper nail has no threads, so it mainly relies on its own shape to provide strong support during insertion. The manufacturing process may include cutting and forming copper materials to obtain the desired straight nail shape and size.

2.Threaded Copper Nails

The main feature of threaded copper nails is that their surface has a threaded structure, which can be fine thread lines or thicker spiral structures.

Compared to traditional straight nails, it can better embed materials firmly. In the manufacturing industry, threaded copper nails are widely used in situations that require stronger retention and stability.

A threaded copper nail is similar to a screw. Before using threaded copper nails, it is usually necessary to pre drill holes on the target material and create pre threads inside the holes that match the threaded copper nails. Then, it passes through the pre hole by screwing in and forms a tight connection with the target material during the process of combining with the pre thread.

In the manufacturing of vehicles such as cars and airplanes, threaded copper nails are widely used to connect and support various components to ensure the strength and stability of the overall structure.

3.Round head copper nails

Round headed copper nails are a copper connection device with a circular head, designed to disperse pressure at the connection and prevent damage to the material surface.

Round head: The head of a round headed copper nail appears circular, usually spherical or cylindrical. This design helps to evenly distribute the force on the connecting parts and reduce the concentrated pressure on the material surface.

Usually solid design: Most round headed copper nails are solid and have no threads. The application of round headed copper nails in the aircraft, electronics, and automotive industries is relatively limited, mainly because these industries have stricter performance and requirements for connecting components, usually requiring more specialized materials and designs.

4.Copper rivets

A rivet is a mechanical connection used to join and secure two or more materials. It uses the riveting process to hold the material tightly together to form a strong connection. Rivets are widely used, especially in structures that require high strength, corrosion resistance and reliability, such as aerospace, automotive manufacturing and construction.

Different types of rivets are suitable for a variety of different scenarios:

Solid rivet:

This is the most basic type of rivet and is usually made of a uniform solid metal material.

For connections requiring high strength and reliability, such as in aerospace.

Open rivets (blind rivets) :

Open end rivets, also known as blind rivets, are a type of special metal fasteners widely used in the manufacturing industry. Especially in the fields of aerospace, electronics, and shipbuilding, these rivets play a crucial connecting role. Their design is unique, with a tubular structure containing a central axis. The manufacturer cleverly inserted the open rivets into the pre drilled holes on the parts, achieving a sturdy connection of the parts.

Some other common types of blind rivets include:

1. Twist Lock Rivets:

Knob rivets are known for their unique knob design, which provides additional connection security through twist locking. This design makes it very useful in applications that require resistance to vibration and vibration, ensuring the robustness of the connection.

It is particularly suitable for assemblies that need to move frequently or are affected by external vibrations, such as aircraft interior equipment and high-speed moving machinery.

2. Nested Rivets:

The nested rivet uses a sleeve structure to make it more compact when connected. This design can increase the density of the connection and is especially suitable for applications where space is limited.

It is common in areas where high-density connections need to be achieved in a limited space, such as compact component arrangements in electronic devices.

3. Spiral Rivets:

Spiral rivets are notable for their spiral structure, a design that increases the surface area of the connection and provides greater tensile strength.

In engineering applications requiring large tensile loads, such as bridge structures and other applications requiring strong tensile support.

Rivet nut:

Unlike ordinary rivets, rivet nuts have an internal threaded structure that can be matched with nuts.

Provides additional flexibility where subsequent threaded connections are required.

Multi-head rivets:

This is a type of rivet that forms multiple riveting heads in a single riveting process to improve the uniformity and strength of the connection.
Suitable for applications requiring a larger connection surface area.
