Stainless Steel Self-Drilling Screws
Product Overview
The SS410 Square Drive Pan Head Self-Drilling Screw is a high-efficiency self-tapping fastener specifically designed for thin sheet metal connections. It features an ANSI-standard #10-16 coarse thread specification with lengths ranging from 12mm to 25mm. Constructed from heat-treated 410 stainless steel, it offers a superior combination of high strength, high hardness, and moderate corrosion resistance. With a built-in self-drilling point, it enables "pre-drill free" installation. Combined with a pan head and square drive design, it provides optimal installation efficiency, structural integrity, and ease of use, making it ideal for various light steel structures and metal assembly applications.
Product Applications
Light Steel Construction: Ideal for securing colored steel tiles, sandwich panels, roofing/wall sheets, and purlins.
Metal Sheet Fabrication: Suitable for connecting automotive sheet metal, ventilation ducts, shelving units, enclosures, and cabinets.
Outdoor Installations: Reliable fastening for billboards, guardrails, light boxes, fencing, and other outdoor infrastructure.
Industrial Assembly: Perfect for securing metal components in home appliance housings, equipment racks, and electrical control cabinets.
Product Features
Efficient Self-Drilling: Equipped with a precision-engineered drilling point, it can penetrate 1-5mm metal sheets directly without the need for pre-drilling. This "drill-tap-fasten" all-in-one process significantly boosts construction efficiency.
High-Strength Material: The heat-treated 410 stainless steel provides high hardness and excellent toughness, delivering superior drilling capability and tensile strength while resisting cam-out and breakage.
Square Drive: Ensures uniform torque transmission and prevents slippage during high-torque tightening. It is fully compatible with power tools for stable and reliable installation.
Pan Head Design: Provides a large bearing surface for a stable contact area after installation, resulting in a clean, professional appearance that balances functionality with aesthetics.
Versatile Specifications: The #10-16 coarse thread offers a strong grip, while the 12-25mm length range allows for flexible adaptation to various material thicknesses and connection requirements.
