Drywall screw | DIN18182:

The role of drywall screws is very important. In the world, there are examples of houses collapsing due to poor quality of drywall screws; there are also examples of many serious accidents caused by poor quality of drywall screws. Drywall nails, also known as wallboard nails, are used to install various gypsum boards, ceilings, lightweight partitions, light steel keels, etc.

The production process of drywall screws typically involves the following steps. 

1. Wire Drawing: The first step is wire drawing which involves the production of steel wire of the required diameter. The wire used for drywall screw manufacturing is typically made from low carbon steel.

2. Annealing: The steel wire is then annealed to make it more malleable and easy to work with. This is done by heating the wire to a high temperature and then gradually cooling it down.

3. Heading: The wire is then fed into a header machine which cuts it into the desired length and shapes the head of the screw.

4. Pointing: The next step involves pointing the screw by grinding the tip to a sharp point. This is done to make it easier to insert the screw into the drywall.

5. Threading: The screw is then threaded using a machine that rolls the wire between two dies. The threading process ensures that the screw will fasten securely into the drywall.

6. Coating: Once the screws have been threaded, they are coated with a zinc, phosphate or black oxide finish to prevent rust and increase durability.

7. Quality control: The final step involves inspecting the screws for defects such as cracks, missing threads or other imperfections. Only screws that meet the necessary quality standards are packaged and distributed to customers.
