Product Overview
Blue-coated hexagon flange self-drilling screw (commonly known as "self-drilling screw/concrete self-tapping screw") is a high-efficiency integrated fastener specifically developed for hard substrates. It breaks through the limitation of traditional screws that require "pre-drilling and step-by-step installation", integrating the three functions of drilling, tapping, and fastening into one unit, allowing direct penetration through metal sheets or screwing into concrete to complete the installation process in a single operation.
Its iconic blue anti-corrosion coating, combined with a high-strength carbon steel substrate, ensures excellent weather resistance and rust prevention while maintaining connection strength. It is widely used in construction, steel structures, curtain walls, photovoltaics, and many other fields, making it a highly efficient and durable standardized fastener for engineering construction.
Product Applications
Widely used in steel structure workshops, color steel tile roofing, curtain wall keels, photovoltaic brackets, outdoor equipment, and light-duty concrete fixing, among other scenarios. It is a highly efficient and durable standardized fastener for construction engineering.
