The manufacturing process of nails mainly includes wire drawing, cold heading, polishing and other processes. The manufacturing process of nails is relatively simple. The raw material for nail production is round plate, which is round steel in a plate. After drawing, pull out the diameter of the nail rod, and then make the nail tail and nail tip by cold upsetting, and then polish the finished product. If the nail surface needs electroplating or blackening, these procedures can be added.

Nail classification

Wood screw: also known as wood tooth screw. Compared with other nails, it is easier to combine with wood, and is mainly used for combining metal and other materials with wood materials.

Self-tapping screw: the screw body has deep thread, high hardness and low price, which can better combine two metal parts than other screws. It is used to connect and fix multi-metal components, such as aluminum alloy doors and windows.

Steel row nails: The characteristics of steel row nails are novel and unique design, quick effect, good engineering quality and wide application. It is an ideal substitute for ordinary round nails. Use: making furniture, sofa, wooden case and various wooden products.

Cement nail: the shape is similar to round nail, and the head is slightly thick. The cement steel nail is made of high-quality steel, which has the advantages of hardness and bending resistance, and can be directly nailed into concrete and brick walls. Common specifications are 7~35mm.

Straight nail: straight nail Use: plywood and Flat noodles in decoration industry. Steel nails, such as wooden rattan furniture in the manufacturing industry, are made of high-quality 45 # carbon steel, with unique design, reasonable structure and beautiful appearance, and are suitable for the connection of light wooden keel.

The length of nails used shall be 2.5 to 3 times the thickness of the workpiece to be nailed. In order to increase the connection firmness, the nails should be inclined to form a dovetail inclined nail combination to produce a hook effect. When hammering wooden nails, the long end should be sawed off first to reduce wood splitting. When hammering hardwood nails, a nail hole should be drilled first, and the diameter of the hole should be slightly smaller than the diameter of the nail. At least two standard nails shall be driven into each joint surface to ensure firm connection.
