Frequently Asked Questions

Q: What are the main benefits of Wafer Head Self-Drilling Screws?

They combine a wide head for better clamping pressure with a self-drilling tip that eliminates the need for pre-drilling, significantly increasing assembly efficiency in metal work.

Q: How does the zinc plating compare to ordinary galvanized products?

Our advanced surface treatment technology provides a denser, more uniform coating, resulting in anti-corrosion and weather resistance that is 5 times stronger than standard galvanized screws.

Q: Can these screws be used for heavy-duty steel structures?

Yes, since we use premium raw materials from large domestic steel companies, our screws meet the stringent requirements for high-strength applications in metal construction.

Q: What prevents the screwdriver from slipping during installation?

The screws feature a deepened cross hole design, which provides a more secure grip for the driver bit, preventing cam-out and slippage during high-torque fastening.

Q: Which industries commonly use these fasteners?

They are widely used in the manufacturing of metal doors, windows, architectural decoration, and general industrial metal-to-metal assembly.

Q: Are these screws compatible with various metal thicknesses?

Our self-drilling screws are designed with high-precision German technology to penetrate various metal thicknesses rapidly while maintaining a strong anchoring force.
