2.How are common iron wire nails made?

2.1 Raw Material of Wire Nail

High quality wire rod(SAE1008) is the most common primary raw material selection for making common iron wood nails.It is usually used by making wire rods into low carbon steel nail wire(Q195 Q235) for common construction wire nails manufacturing process.The nail wire used for iron nails should possess specific qualities such as strength, durability, and the ability to be easily shaped into nails.


2.2 Wire Drawing
    A. Process of wire drawing 

►Heating (Optional - Annealing):

In some cases, the raw material wire, may undergo an annealing process before wire drawing. Annealing involves heating the wire to a specific temperature and then slowly cooling it. This process relieves stress within the material, making it more malleable and easier to work with wire drawing processes.
Annealing helps in reducing hardness and enhancing the ductility of the wire, ensuring better drawing characteristics and minimizing the risk of breakage during the drawing process.

►Drawing:

The drawn wire, whether annealed or not, is then fed into the wire drawing machine. The machine consists of a series of dies or drawing plates through which the wire passes.
The wire drawing machine exerts tension on the wire and pulls it through the dies, which have successively smaller diameters. 

This drawing process is repeated successively through multiple dies until the wire reaches the desired diameter or gauge required for the intended application.

►Cooling:

After the drawing wire has been drawn to the specified diameter, it may undergo a cooling process. The drawn wire is allowed to cool down to room temperature.
Controlled cooling helps in stabilizing the wire's structure and properties, ensuring it retains the common wire nails desired characteristics achieved during the drawing process.


    B. Wire diameter control 

♦ Precision in controlling the wire's diameter is critical in the wire drawing process.
♦ Monitoring instruments and gauges are employed to measure the wire's diameter continuously during drawing. These measurements ensure that the wire's diameter consistently meets the specified dimensions required for the production of common wire nails.
♦ Adjustments in drawing speed, tension, and the number of drawing passes through the dies are made as necessary to maintain the accuracy of the wire's diameter.

►Conversion of different sizes

Nowadays, people usually use inches or "mm" to indicate the length of the nail, and BWG(gauge) is used to indicate the wire diameter of the nail, which is the width of the nail shank.

In earlier times, people used "D" to indicate the size of a nail. The letter "D"  is a traditional term for nail length. The number before the "D" indicates the shank length of the common iron wire nails.

In construction or woodworking projects,people often use 8d common iron wire nails,so what size is an 8d common iron wire nail?

The 8d common iron wire nail size is 2-1/2 inch length and 10/11 bwg gauge.

What is the length and diameter of a 20d common construction wire nail?

It is 9-gauge shank, 0.148-inch shank diameter and 4"/101.6mm shank length.

Other sizes can be converted to different specifications by referring to the table above.

2.3 Common Iron Wire Nail Making
   A. Wire straightening and cutting

The process starts with wire straightening and cutting. The drawn wire, which has been previously processed through wire drawing to attain the required diameter, undergoes straightening to eliminate bends or irregularities.
Subsequently, the straightened wire is cut into shorter lengths, forming individual nail blanks that will be used to create the nails.


   B. Feeding wire into the nail-making machine

The prepared nail blanks are then fed into the nail-making machine. This machine is specifically designed for the automated production of nails.The nail making machine's mold presses the drawing nail wire into the common iron wire nails with smooth shank,sharp diamond point and round/flat/checkered head.

The machine receives the individual nail blanks and guides them through the nail-making process, ensuring precision and efficiency in the nail manufacturing.
