Frequently Asked Questions

Q: What makes self-drilling screws different from standard screws?

Self-drilling screws feature a drill-shaped point that allows them to drill their own hole through metal, eliminating the need for pre-drilling and significantly speeding up installation.

Q: Are these fasteners suitable for outdoor steel structures?

Yes, thanks to our advanced surface treatment technology, these screws offer exceptional weather resistance and anti-corrosion properties compared to ordinary products.

Q: Can these screws be used on aluminum profiles?

Absolutely. Our hexagonal drill tail screws are specifically designed to connect metal-to-metal, including aluminum profiles, light steel keels, and wooden keels.

Q: How does the dovetail design improve efficiency?

The dovetail design optimizes the cutting angle at the tip, which enhances the attack speed and penetration force, allowing for faster drilling into thick metal sheets.

Q: What steel standards are used for the raw materials?

We source all raw materials from leading domestic steel companies to ensure that every bolt meets the stringent requirements for high-strength structural fasteners.

Q: What are the primary applications for these fasteners?

They are primarily used for fixing color steel tiles in steel structures, as well as connecting simple building thin plates and various metal-to-metal junctions.
