Stainless Steel Blue Painted Head Hex Flange Self-Drilling Screws

Our screws are professionally crafted with high-quality stainless steel substrate and high-standard blue baking paint surface treatment, integrating decorative painted head, heavy-duty Hex Flange Head and high-hardness Self-Drilling Point, specially designed for decorative construction and exposed installation projects. Different from ordinary single-functional fastening screws, this product combines practical fastening performance and aesthetic decorative performance perfectly. The screw head adopts advanced baking paint technology, with smooth and flat surface, uniform and bright blue color, no color difference or burrs, presenting an exquisite and neat installation effect after construction, which can perfectly match various colorful building decoration styles. The high-adhesion paint layer has strong wear resistance, anti-ultraviolet and anti-aging ability, effectively avoiding color fading, peeling and rusting caused by long-term outdoor exposure. The integrated hex flange head provides large uniform pressure-bearing area, preventing plate sinking and loosening during fastening. The hardened self-drilling tip has strong penetrating performance, capable of fast drilling and fixing on light steel plates, color steel plates and wood decorative panels without pre-drilling. With dual protection of stainless steel substrate and painted layer, these screws maintain stable fastening strength and beautiful appearance in long-term outdoor use, becoming ideal decorative fastening fasteners for high-standard building projects.
