Pan Head Self-Drilling Screws
Product Overview
SS410 square drive pan head self-drilling screw (USA Standard) is a high-efficiency self-tapping fastener specifically designed for connecting thin metal sheets. It adopts USA Standard #10-16 coarse thread specifications, with lengths covering 12-25mm, and is made of 410 stainless steel strengthened by heat treatment, combining high strength, high hardness, and moderate corrosion resistance. The tail features an integrated self-drilling cutting edge, enabling "pre-drill-free" direct installation. Combined with the pan head and square drive design, it balances installation efficiency, connection strength, and ease of use, making it widely suitable for various light-gauge steel structures and metal assembly scenarios.
Product Applications
Light-gauge steel structure projects: Fixing and installation of color steel tiles, sandwich panels, roofing/wall panels to purlins.
Metal sheet metal fabrication: Splice connections for automotive sheet metal, ventilation ducts, shelving, cabinets, and enclosures.
Outdoor facility installation: Fastener connections for billboards, guardrails, light boxes, fences, and other outdoor facilities.
Industrial equipment assembly: Fixing of metal components in home appliance housings, equipment racks, electrical control cabinets, and similar scenarios.
Product Features
Efficient self-drilling: The integrated cutting edge at the tail can directly penetrate 1-5mm metal sheets without pre-drilling, achieving "drill – tap – lock" in one step, greatly improving construction efficiency.
High-strength material: SS410 stainless steel, after heat treatment, offers high hardness and good toughness, with excellent drilling capability and tensile strength, and is resistant to thread stripping and breakage.
Square drive: Provides uniform torque transmission, enabling high-torque tightening without slipping, compatible with power tools for stable and reliable installation.
Pan head design: Offers a large load-bearing surface, providing a stable contact area after installation with a clean and aesthetic appearance, balancing functionality and visual appeal.
Strong specification adaptability: #10-16 coarse threads provide a strong grip, with multiple lengths from 12-25mm available, allowing flexible adaptation to different panel thicknesses and connection requirements.
