Product Overview
Square drive wafer head color zinc self-drilling screw is a high-efficiency self-tapping fastener specifically designed for metal sheet connections, with model specifications covering 10-16×16-30, suitable for various conventional construction scenarios. The product uses high-strength carbon steel as the substrate, combined with a color zinc passivation coating, while integrating a self-drilling cutting tip structure, wafer-type head, and square drive design, enabling a pre-drill-free work process that completes drilling – tapping – locking in one operation. It balances installation efficiency, connection strength, and anti-corrosion performance, making it a general-purpose high-efficiency fastener for construction, sheet metal, steel structures, and other fields.
Product Applications
Fixing of color steel tiles and wall color steel sheets in steel structure workshops, as well as installation of roofing and wall enclosure systems;
Rapid assembly of light steel keel partition walls and curtain wall panels, as well as connection and fixing of aluminum alloy door/window frames and sheet metal parts;
Installation of thin metal components such as photovoltaic brackets, simple steel structures, ventilation ducts, and equipment housings;
Various indoor and outdoor metal sheet splicing scenarios require pre-drill-free and high-efficiency fastening, suitable for most conventional construction and industrial installation requirements.
