Description
A2-70 / A4-80 Stainless Steel ISO 7380-2 Flanged Button Head Torx/Hex Screws
ISO 7380-2 is a globally recognized standard for hexagon socket button head screws that feature an integrated flange or "collar" under the head. Unlike the standard ISO 7380-1, the ISO 7380-2 design eliminates the need for separate washers, providing a streamlined, low-profile fastening solution. Manufactured from high-quality stainless steel (typically Grade A2-70 or A4-80), these machine screws are designed for applications that require a combination of aesthetic appeal, security, and a wide load-bearing surface.
Core Features
  • Exceptional Hardness: Unlike 300-series stainless steel, 410 grade can be hardened through heat treatment. This allows the screw to penetrate carbon steel sheets and harder substrates without the tip burning out.
  • Time-Saving Efficiency: The integrated drill point eliminates the need for pre-drilling and hole alignment, drastically reducing installation time and labor costs.
  • Corrosion Resistance: Offers reliable protection against atmospheric corrosion, water, and mild chemicals, making it superior to standard carbon steel fasteners in humid environments.
  • High Torque Strength: The hexagonal head design ensures maximum torque transmission and prevents cam-out during high-speed installation with power tools.
  • Integrated Sealing: Often used with EPDM bonded washers to provide a leak-proof seal, which is critical for outdoor and roofing applications.
Application Scenarios
  • Automotive & Transportation: Used in interior trim, dashboard assemblies, and external bodywork where a smooth, decorative finish is required.
  • Industrial Machinery: Ideal for guarding, paneling, and enclosures where space is limited and a low-profile head is necessary.
  • Electronics & Appliances: Widely used in the assembly of consumer electronics, server racks, and household appliances due to its compact and neat appearance.
  • Furniture & Architecture: Common in high-end furniture assembly and architectural fixtures where the screw head remains exposed.
  • Bicycles & Sporting Goods: Used for mounting accessories and structural components that require high-strength fastening with minimal wind resistance.
