Products Process
Material Selection:
High-quality steel is chosen to meet the DIN 7981 specifications. The material is often treated to enhance strength and prevent rust.
Cold Heading:
The screws are formed through a cold heading process, which shapes the screw head without heating. This ensures high strength and maintains the integrity of the material.
Thread Rolling:
Precision thread rolling machines create the self-tapping threads. This method enhances thread strength while reducing material waste and improving surface finish.
Head Formation:
The round pan head is formed to provide a wide bearing surface, ensuring even distribution of load and minimizing the risk of material deformation during installation.
Point Formation:
The self-tapping point is designed to enable easy penetration into various substrates, allowing for quick and efficient installation.
Surface Treatment:
A finish of black oxide, zinc plating, or nickel plating is applied to improve corrosion resistance, providing options for different aesthetic and environmental requirements.
Quality Control:
Rigorous quality control measures are implemented throughout the manufacturing process, including dimensional checks and tensile strength testing to ensure compliance with DIN 7981 standards.
