Products Process
Material Selection: The screws are made from high-quality carbon steel, stainless steel, or alloy steel to ensure high strength, corrosion resistance, and durability.
Cold Forging: The raw material is shaped using cold forging techniques to create the screw's body, ensuring precision and enhanced tensile strength.
Self-Drilling Tip Formation: The drill point is formed with precision, allowing the screw to easily penetrate materials without the need for pre-drilling.
Thread Rolling: The threads are rolled onto the screw's shaft, creating sharp, uniform threads that ensure a strong and secure hold.
Truss Head Shaping: The wafer truss head is carefully formed to provide a larger surface area for better distribution of pressure, preventing material damage.
Heat Treatment: The screws undergo a heat treatment process to improve their hardness, wear resistance, and strength, ensuring a long-lasting, reliable fastener.
Coating: A corrosion-resistant coating, such as zinc plating, black oxide, or galvanizing, is applied to the screws for protection against rust and environmental damage.
Quality Control: Rigorous quality checks are performed to ensure the screws meet high standards of dimensional accuracy, tensile strength, and surface finish.
