Hopefully, the pictures above can help you understand their appearance.

Features of Coil Nails

Uses of coil nails

Construction

Used for timber frame construction, roof truss fixing, and wall panel installation, it quickly connects wooden components and improves construction efficiency.

Packaging and Logistics

Securing panels in pallet and crate construction, or for securely packaging large goods to ensure stable transport.

Gardening and Fencing

Installs wooden fencing, fences, garden supports, and more, efficiently connecting timber and frames for outdoor use.

Furniture Manufacturing

Used for splicing some solid wood furniture frames and decorative materials such as gypsum board, it helps secure panels or mortise and tenon joints, enhancing overall stability.

Types of coil nails

Types: usually they can be divided into many types according to their uses and shapes, such as plain nails, threaded nails, ring nails, etc.

Pattern nails: nails without nail heads, steel row nails: novel and unique design, code nails (K nails, N nails): commonly used for fixing sofas, leather, and boards, cement steel nails: similar to round nails, but with thicker heads, common specifications are 7~35mm. Wood tooth screws: suitable for connecting metal and wood.

2. Classification by shape

Smooth rod coil nails: smooth surface, no threads or ring patterns, ring pattern coil nails: with ring patterns on the surface, used in occasions requiring strong fastening. Threaded coil nails: with threads on the surface, suitable for occasions with greater tension

3. Classification by material

Carbon steel coil nails are made of carbon steel and are used for general wood and plastic connections. Stainless steel coil nails have excellent corrosion resistance and oxidation resistance.

4. Classification by length, diameter, and head shape

For example, according to length, it can be divided into short nails, medium nails, long nails, etc.; according to diameter, it can be divided into thin nails, medium nails, thick nails, etc.; according to head shape, it can be divided into flat head nails, round head nails, flat head nails, etc.

What tools and equipment are needed for coil nail installation?

1. Coil nail gun: it is the main tool for installing coil nails.

2. Coil nail: it is the core fastener in the installation process.

3. The coil nail clamp: it is used to clamp paper or other thin materials so that they can be fixed with coil nails. There are two types of metal clamps and plastic clamps.

4. The coil nail shear: it is used to cut the nails to a more suitable length.

5. Safety equipment: such as safety glasses, protective gloves, etc.

Common specifications

Common length specifications include 23/8 inches (about 60 mm), 3 inches (about 75 mm), 31/4 inches (about 82.5 mm), etc., while diameter specifications include 0.113 inches (about 2.87 mm), 0.12 inches (about 3.05 mm), 0.131 inches (about 3.33 mm), etc.

 

The following are some specific coil nail models and their detailed specifications.

1) 2.3*50MM Coil Nail

This is a pneumatic pallet nail with a threaded or smooth rod design, suitable for the furniture manufacturing and woodworking industries.

2) 7~35mm Steel Row Nail

The design is novel and unique, and the effect is fast. It is an ideal choice for making furniture, sofas, wooden boxes, and various wooden products.

3) Threaded/ringed/smooth rod coil nails of various diameters and lengths

Such as 2.1*32mm, 2.1*38mm, 2.1*45mm, 2.1*50mm, 2.3*57mm, 2.5*64mm, etc. They have different diameters and lengths, suitable for different fastening needs and occasions.

 

The following are the commonly used specification terms for purchase.

15 degree coil nails, 1 1 2 ring shank nails, 3 1 4 coil framing nails, 3 coil nails，duofast nails, 1 3 4 stainless steel ring shank nails, 1 1 2 coil roofing nails, 1 coil roofing nails, stainless coil siding nails, 2 3 8 coil nails, 2 coil nails, 2 1 2 siding nails, 3 inch coil nails…

Coil nails packaging

Coil nails are usually packaged in rolls, and each roll contains a certain number of coil nails. Common quantity specifications include 400/300/250 pieces/roll, etc. Usually, box specifications include 40/36/30/24/20/18 rolls/box.

1. Carton

Common packaging materials, are widely used because of their low cost, easy access, and recyclability. Cartons can provide certain protection to prevent coil nails from being damaged during transportation.

 

2. Plastic bags

Used to further protect coil nails from environmental factors such as moisture and dust. Plastic bags are usually used in combination with cartons to form double protection.

 

3. Blister packaging

A more advanced packaging method made of materials such as PVC and PET. Blister packaging has the characteristics of light weight, corrosion resistance, moisture resistance, tensile resistance, and high strength, which can better protect coil nails.
This packaging method is often used on occasions where the appearance and performance of coil nails are required to be high.

Coil nails price

The price range is wide, and the overall price depends on the specific type, specification, and quantity of coil nails.

1. Quality: Superior quality usually has a higher price.

2. Specifications: This includes length, diameter, head shape, etc., and the price of coil nails of different specifications will also vary.

3. Material: The materials of coil nails are mainly carbon steel, stainless steel, etc., and coil nails of different materials have differences in corrosion resistance, strength, etc., so it is also one of the influencing factors.

4. Production process: For example, the price of coil nails that have undergone special treatments (such as galvanizing, anti-corrosion, electrophoresis, bright, and painting, etc.) will be slightly higher.
