(SUS304/316+410) Bi-metal Pan Head Self Drilling Screw For Metal Sheets

Product Description:

Bi-Metal Phillips Pan Head Self-Drilling Screws are high-efficiency self-tapping, self-drilling fasteners designed for connections between metal sheets and wood/board structures, widely used in steel structures, color steel tile installation, equipment fixing, and renovation projects. Made with bi-metal composite technology, the drill tail is made of high-hardness alloy steel, while the shank is made of premium carbon steel/stainless steel. Available with Brass,zinc or Dacromet finishes, they offer excellent corrosion, wear, and weather resistance for outdoor, humid, and mildly corrosive environments. The screws feature a Phillips pan head design, compatible with common screwdrivers and power bits for convenient installation. The self-drilling tip penetrates metal sheets directly without pre-drilling, ensuring smooth driving without slipping and secure connections, making them ideal solutions balancing efficient construction, corrosion resistance, and versatility in steel structure and panel connections.

Key Features & Advantages:

1.Bi-Metal Technology Dramatically Improves Drill Tail Durability

The high-hardness alloy steel drill tail penetrates steel sheets without tip breakage, while the tough shank resists fracture. They last far longer than ordinary self-drilling screws, reducing breakage and tip failure during construction to lower rework rates.

2.No Pre-Drilling Required for Significant Efficiency Improvements

The self-drilling tip penetrates metal sheets directly, eliminating pre-drilling steps and improving construction efficiency by over 50%. Fast single-person installation reduces labor costs for bulk steel structure projects.

3.Corrosion & Wear-Resistant Finishes for Long Outdoor Service Life

Brass/Zinc/Dacromet coatings offer excellent rust and wear resistance, suitable for outdoor, humid, and mildly corrosive environments. They resist rust and peeling, lasting far longer than ordinary zinc-plated screws to reduce maintenance costs.

4.Phillips Pan Head for Flexible & Versatile Installation

Compatible with common screwdrivers and power bits with reduced slipping, these screws are ideal for mass production and on-site construction with low threshold, adapting to different construction scenarios.

5.Full Threads for Secure Engagement & High Anti-Loosening Pull-Out Strength

The full thread structure provides tight engagement with the substrate, offering high pull-out resistance to prevent loosening. Suitable for heavy-load, long-term applications like steel structures and color steel tiles to improve structural stability.

6.Wide Range of Sizes for One-Stop Procurement

A full range of sizes covers different steel sheet thicknesses and connection needs, enabling one-stop procurement to reduce supplier management costs, ideal for bulk purchases in steel structure and renovation projects.

7.Strong Versatility for Multi-Substrate Connections

Suitable for steel-to-steel, steel-to-wood, and steel-to-color steel tile connections, offering strong versatility to reduce SKU management costs and meet installation needs of different projects.

Common Application:

• Steel Structure Engineering: Plate fixing in light steel structures, steel component connections, and factory construction, adapting to different steel sheet thicknesses.
• Color Steel Tile/Roofing Projects: Installation and fixing of color steel tiles, sandwich panels, and roof sheets, suitable for outdoor and humid environments.
• Equipment & Electrical Installation: Connection and fixing of chassis cabinets, electrical enclosures, and metal equipment, suitable for composite connections between metal sheets and plastic/wood.
• Renovation & Indoor Projects: Installation and fixing of metal keels, light steel keels, ceilings, and partitions, suitable for connections between metal and wood/boards.
• Outdoor & Anti-Corrosion Projects: Installation and fixing of outdoor steel structures, guardrails, and safety nets, suitable for humid and mildly corrosive environments.
• Repair & Renovation Projects: Connection and fixing in old steel structure renovation, equipment maintenance, and panel reinforcement, suitable for non-standard holes and aging sheets.
• Other General Scenarios: All metal sheet and substrate connection applications requiring self-drilling, no-pre-drilling, and anti-corrosion reinforcement.
