Products Process
Material Selection: The screws are made from high-quality steel, stainless steel, or other alloys based on customer specifications, offering superior strength and corrosion resistance. Materials are carefully selected to meet industry standards.
Cold Heading: The raw material, usually in the form of wire, undergoes cold heading to form the basic shape of the screw. This process ensures uniformity and the right mechanical properties, ensuring strength without compromising material integrity.
Thread Rolling: Threads are rolled onto the screw shaft using a thread rolling process, which creates sharp, precise threads. This technique improves tensile strength and helps prevent thread stripping during tightening.
Pan Head Formation: The pan head is formed through a heading process. This design provides a larger surface area for a secure grip with a screwdriver, while the collar beneath the head ensures a tight, stable connection with the surface.
Surface Treatment: The screws are treated with surface coatings such as zinc plating, passivation, or black oxide for enhanced corrosion resistance and durability. These treatments are particularly valuable in harsh or outdoor environments.
Quality Control: Each screw undergoes rigorous quality control tests to verify dimensions, tensile strength, and surface finishes. These checks ensure that the product meets the required mechanical properties and complies with standards such as DIN 967.

FAQ
What materials are these screws made from?
These screws are typically made from high-strength steel, stainless steel, or other alloys, offering excellent durability and corrosion resistance. Custom materials are available upon request.
Are these screws suitable for outdoor use?
Yes, when coated with surface treatments such as zinc plating or passivation, these screws are highly resistant to corrosion, making them ideal for outdoor environments.
What is the benefit of the collar under the head?
The collar beneath the pan head improves the screw's ability to hold components in place by preventing the screw from sinking too deeply into the material, ensuring a more secure fit.
What is the cross-recessed drive for?
The cross-recessed drive allows for better torque transmission during installation, minimizing the risk of stripping the screw head and providing a more secure grip with the screwdriver.
Do these screws meet any standards?
Yes, these screws are manufactured according to DIN 967 and other relevant standards, ensuring that they meet international quality and performance requirements.
What sizes are available for these screws?
These screws are available in sizes ranging from M3 to M20 in diameter, with lengths typically ranging from 10mm to 100mm. Custom sizes can be produced based on specific needs.
What surface treatments are available?
These screws are available with a variety of surface coatings, including zinc plating, passivation, and black oxide, to enhance their resistance to corrosion and wear.
What is the tensile strength of these screws?
The tensile strength varies depending on the material used. Steel-based screws typically offer a tensile strength of 400–900 MPa, while stainless steel offers even higher strength and corrosion resistance.
Can I use these screws in high-vibration environments?
Yes, the collar design and robust thread rolling process ensure that these screws maintain their holding power even under conditions with frequent vibration, such as in automotive or machinery applications.
