Nail definition and classification

A nail is a pointed piece of hard metal (usually steel) used to hold things such as wood in place. Hammers drive nails into objects, and more recently, electric nail guns and gas nail guns. The reason why the nail can stabilize the object is by its own deformation and hooked on it, and by friction. Nails are one of the most common things in decorating. Iron nails are also called iron nails, and steel nails are also called steel nails. In engineering, carpentry, and construction, a nail is a pointed piece of hard metal (usually steel) that is used to hold things such as wood in place. Hammers drive nails into objects, and there are also electric nail guns and gas nail guns. Nails are therefore able to stabilize objects by being hooked to them through their own deformation, as well as by friction.

Nails come in different shapes for many purposes, the most common nail is called a “wire nail”, and other common nail names are pins, thumbtacks or curveheads. Nails are widely used, the use of more scenarios, the general aircraft carrier rivet price is more expensive, the price of ordinary nails is cheaper¬†peg.

Nail usage: no nail head nails, no nail marks after laying, suitable for advanced decoration industry.A nail that is indispensable in construction

Steel gang nails

Wood screw

Also known as wood teeth screw. It is easier to combine with wood than other nails, and is used in the combination of metal and other materials with wooden materials.

Twist nail

The nail body is shaped like a twist, the head is round and flat, the head of a cross or a font, and the bottom is a pointed bottom. The nails are particularly strong. Suitable for some places that need strong pinning force, such as drawers, wooden ceiling boom, etc., common specifications from 50 to 85mm have a variety of specifications.


It is a nail with sharp ends and a smooth surface in the middle. Splicing nails are easier to merge and fix wood than other nails, especially suitable for use as pins when the board is combined, and the common specifications are 25~120mm.

Tapping screw

The body screw is deep, high hardness, cheap, and 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.

Shoot nail

It’s similar to a cement nail, but it’s shot from a gun. Relatively speaking, nail fastening is better and more economical than manual construction. It is also easier to construct than other nails.

For the binding of paper documents, etc., generally made of iron or copper, plated with nickel or nickel-zinc alloy to prevent rust.


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

Straight nail

Straight nail application: decoration industry of plywood, strip board installation. Furniture manufacturing wood assembly inlaid rattan and other steel nails: the use of high-quality 45# carbon steel manufacturing, unique design, reasonable structure, exquisite appearance, suitable for light wood keel connection.

Special steel nail

Special steel nails: The use of high-quality 45# steel manufacturing with high strength can be directly nailed into the ordinary brick wall, 260#-280# cement mortar block, silicate and other structures, is the ideal building installation, decorative riding nails (U-shaped nails) uses: mainly used for fixing metal plate mesh, wire mesh and indoor hanging line, can also be used for fixing steel wire binding wooden boxes.
