Manufacturing Process

The production process of Hexagon Head Self Drilling Screw involves the following steps:

1. Raw Material Inspection: The raw materials, usually carbon steel or stainless steel, are inspected for their quality and authenticity.

2. Heading: The steel wire is fed into a heading machine which shapes the wire into the head of the screw.

3. Threading: The threaded portion of the screw is created by passing it through a thread rolling machine that applies pressure to the steel wire, shaping it into the desired thread pattern.

4. Drilling: A sharp point is added to the end of the screw, along with flutes that help remove excess material as the screw is drilled into the workpiece.

5. Heat Treatment: Depending on the application of the screw, it may go through a heat treatment process to harden the steel and increase its strength.

6. Plating: The screw may be plated with a coating, such as zinc or nickel, to provide corrosion resistance and improve its appearance.

7. Final Inspection: The finished screw undergoes a final inspection to ensure it meets the necessary quality and performance standards.

8. Packaging: The screws are packaged into boxes or bags, and labeled for distribution to the customer.
