Product Overview
This product is a hexagon flange head self-drilling and self-tapping screw, manufactured from a carbon steel substrate and surface-treated with a color zinc passivation anti-corrosion coating. The screw integrates four major structures: a hexagon drive head, an integral flange sealing washer, self-tapping threads, and a drill-point cutting tip. Without the need for pre-drilling, it can complete drilling, tapping, and locking in a single operation. It is a dedicated heavy-duty fastener for light-gauge steel buildings and metal steel structures, suitable for connecting various metal components such as medium-to-thick steel plates and multi-layer color steel sandwich panels, combining installation convenience with sealing and waterproof performance.
Product Applications
Light-gauge steel engineering: Fixing of color steel tiles, sandwich panels, and C-shaped steel purlins in steel structure workshops, warehouses, and canopies;
Outdoor facilities: Assembly of greenhouse steel frames, billboards, metal guardrails, and sunshade structures;
Mechanical and electrical installation: Fastening of ventilation ducts, distribution boxes, and equipment metal brackets;
Decoration and enclosures: Splice joints for metal partitions, prefabricated iron sheet enclosures, and small steel frame structures.
