What Are The Types Of Nails

In engineering, carpentry and construction, nails refer to pointed hard metals (usually steel), which are used to fix wood and other objects. Hammers drive nails into objects, and there are also electric nail guns. So the nail can stabilize the object, it hooks on it by its own deformation, as well as by friction.

Nails come in different shapes due to their many uses. The most common nails are called "wire nails". In addition, common nail names include pins, thumbtacks or brads. Nails have a wide range of uses and are used in many scenarios. The price of rivets for general aircraft carriers is more expensive, while the price of ordinary nails is cheaper.

The types of nails are as follows:

Steel row nails

Steel row nail features: novel design, unique, fast efficiency, good engineering quality, wide application, etc. It is an ideal replacement product for ordinary round nails.

Steel row nails

Uses: furniture making, sofas, wooden boxes, and various wooden products.

K nail

K nails, code nails, N nails use: furniture manufacturing for sofas, chairs, sofas and leather. Used in the decoration industry for ceilings, thin plates, etc., and used for the outer thin plates in the wooden box industry

Steel nails

It is similar in appearance to round nails, and the head is slightly thicker. However, cement steel nails are made of high-quality steel, which have the advantages of hardness and bending resistance, and can be directly nailed into concrete and brick walls. Common specifications are 7~35mm.

Wood screws

Also known as wood screws. Compared with other nails, it is easier to combine with wood, and it is mostly used in the combination of metal and other materials with wooden materials.

Twist nails

The nail body is like a twist, the head is round and flat, cross or flat, and the bottom is pointed. The nailing force is particularly strong. It is suitable for some places that require strong nailing force, such as drawers, wooden ceiling hangers, etc. The common specifications are from 50 to 85mm and there are many specifications.


It is a nail with pointed ends and a smooth surface in the middle. Splicing nails are easier to combine and fix wood than other nails. They are especially suitable for dowels when combining wood panels. Common specifications are 25~120mm.

Self-tapping screws

The nail body has a deep thread, high hardness, and low price. It can combine two metal parts better than other nails. It is mostly used for the connection and fixing of metal components, such as the production of aluminum alloy doors and windows.

Nail shot

The shape is similar to that of a cement nail, but it is shot from a gun. Relatively speaking, nail fastening is better and more economical than manual construction. At the same time, it is easier to construct than other nails. Nails are mostly used in the construction of wooden projects, such as fine wood making and wooden facing projects.

Split nail

There are mother nails and child nails. The mother nail is a hollow cylindrical shape. The two corners of the bottom will diverge after the child nail is driven; it is generally used to fix various parts on concrete.


For binding paper documents, there are generally two types of iron or copper, with nickel or nickel-zinc alloy plated on it to prevent rust.


Bolts commonly used in decoration projects are mainly divided into two types: plastic and metal, which are used to replace embedded bolts. Suitable for all kinds of wall and ground anchoring building accessories and objects.

Straight nail

Straight nail use: plywood and strip assembly in the decoration industry. Wood-assembled rattan in the furniture manufacturing industry. Steel nails: Made of high-quality 45# carbon steel, with unique design, reasonable structure and exquisite appearance, suitable for light wood keel connection.

Special steel nails

Special steel nails: It is made of high-quality 45# steel with high strength and can be directly nailed into ordinary brick walls, 260#-280# cement mortar blocks, silicate and other structures. It is ideal for building installation and decoration riding nails (U-shaped nails). ) Purpose: Mainly used to fix metal plate mesh, wire mesh and indoor and outdoor hanging wires, and can also be used to fix steel wires for binding wooden boxes. Ordinary round nails are generally only used for construction structures, rough parts, and carpentry. Shooting nails are mainly used for fine wood production and wooden overlay projects.

Floor nails are used for floor paving

Ring nails are mainly used for the surface of fiberboard and gypsum board.

Concrete steel nails are used to connect cement walls, ground and surface materials. Decorative nails are used to fasten the soft bag.

The length of the nail you choose to use should be 2.5 to 3 times the thickness of the workpiece to be nailed. In order to increase the firmness of the connection, there should be an angle when nailing, forming a dovetail diagonal nail combination, producing a hook effect. For wood nailing, the long ends should be sawn off first to reduce wood splitting. When nailing hardwood nails, drill the nail holes first, and the hole diameter should be slightly smaller than the nail diameter. At least two nails that meet the standards should be nailed to each connecting surface to ensure a strong connection.
