High Construction Efficiency, Time and Labor Saving

Self-drilling screws come with an integrated drill bit structure, requiring no pre-drilling. Drilling, tapping and fastening can be completed in one step. They are especially suitable for large-area projects such as color steel tiles, photovoltaic brackets and curtain walls, greatly reducing labor and equipment costs.

Firm Connection, Stable and Durable

Adopting thread and dovetail engagement structure, the screws feature excellent pull-out resistance and shear resistance. They maintain high pre-tightening force after fastening, with strong wind and seismic resistance. They are not easy to loosen during long-term outdoor use, ensuring long-term stability and reliability of engineering projects.

Premium Material, Rustproof and Long-lasting

Made of 1022/SWRCH22A carbon steel with carburizing and quenching treatment, balancing high hardness and good toughness. Multiple anti-corrosion coatings such as galvanizing and Dacromet are available, with salt spray resistance reaching 72–500 hours. Excellent rust resistance enables adaptation to humid, outdoor and other harsh environments.

Wide Compatibility, Multi-scene Application

Applicable to 0.5–6mm thin metal sheets, color steel tiles, light steel keels, ventilation ducts, billboards and more. Widely used in home decoration, industry and outdoor engineering. Complete specifications fully meet various construction requirements.
