How are nails made?
Nails are produced by special machines.

With the help of the machine, very durable carbon steel wire is pulled out and placed on the rotating drum. After continuous pulling, the steel wire that has reached the size is rolled up, cut into truncated bars by the machine, and then sucked into the designated machine by the electromagnet to treat the head and tail of the nail. Under the action of hydraulic tongs, the sharp tail of the nail is made, and then the other end is flattened by a press to press out the nail head, and the nail is manufactured.

In engineering, carpentry and architecture, nails refer to pointed hard metal (usually steel) used to fix wood and other things. Hammer nails into objects, and there are also electric nail guns and air nail guns. Because nails can stabilize objects, they are hooked on them by their own deformation and by friction.

Types and uses of nails:

1, granular nail. Application of pattern nail: no nail head nail, no nail mark after laying, suitable for advanced decoration industry.

2. Steel row nails. Characteristics of steel nail arrangement: novel and unique design, quick effect, good engineering quality and wide application. It is an ideal substitute for ordinary round nails. Uses: making furniture, sofas, wooden boxes and various wood products.

3, K nail, code nail, N nail uses: furniture manufacturing used for sofa chairs, sofas, leather. Decoration industry is used for ceiling, plate, etc. Wooden cases are used to make outer layers.

4. Cement steel nails. The shape is similar to a round nail, and the head is slightly thicker. Cement steel nails are made of high-quality steel nails, which have the advantages of hardness and bending resistance and can be directly nailed into concrete and brick walls. Common specifications are 7~35mm. Cement nails can also be divided into: black cement nails, blue cement nails, colored cement nails, countersunk cement nails, K-type cement nails, T-type cement nails, galvanized cement nails and so on.

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

6. Screw your nails. The nail body is twisted, the head is round and flat, cross or prefix, and the bottom is pointed. The nail force is particularly strong. Suitable for some places that need strong nailing force, such as drawers and wooden ceiling suspenders. Common specifications range from 50 to 85 mm.

7. pinch. It is a nail with sharp ends and smooth middle surface. Split nails are easier to combine and fix wood than other nails, and are especially suitable for being used as pins in jigsaw puzzles. Common specifications are 25 ~ 120 mm.

8. Self-tapping screws. The nail body has deep thread, high hardness and low price. Compared with other nails, it can better combine two metal parts. It is mostly used for the connection and fixation of metal components, such as the production of aluminum alloy doors and windows.

9, nail shooting. It's similar in shape to a cement nail, but it was shot with a gun. Relatively speaking, nailing is better and more economical than manual construction. Meanwhile, it is more convenient for construction than other nails. Nail shooting is mostly used in the construction of wood engineering, such as joinery and wood veneer engineering.

10, split nail. It is divided into a female nail and a female nail. The female nail is hollow and cylindrical, and the two corners at the bottom will diverge after the female nail is driven. It is generally used to fix various parts on concrete.
