Description
ISO 7380-2 Stainless Steel Hexagon Socket Button Head Screws with Collar
ISO 7380-2 Stainless Steel Hexagon Socket Button Head Screws with Collar are globally recognized fasteners featuring an integrated flange or "collar" under the head. This 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 combine aesthetic appeal, security, and wide load-bearing surface capabilities.
Core Features
  • Exceptional Hardness: Unlike 300-series stainless steel, 410 grade can be hardened through heat treatment, allowing the screw to penetrate carbon steel sheets and harder substrates without tip burnout.
  • Time-Saving Efficiency: Integrated drill point eliminates the need for pre-drilling and hole alignment, drastically reducing installation time and labor costs.
  • Corrosion Resistance: Provides reliable protection against atmospheric corrosion, water, and mild chemicals, superior to standard carbon steel fasteners in humid environments.
  • High Torque Strength: 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 leak-proof seals, critical for outdoor and roofing applications.
Application Scenarios
  • Automotive & Transportation: Interior trim, dashboard assemblies, and external bodywork where smooth, decorative finish is required.
  • Industrial Machinery: Guarding, paneling, and enclosures where space is limited and low-profile heads are necessary.
  • Electronics & Appliances: Assembly of consumer electronics, server racks, and household appliances due to compact, neat appearance.
  • Furniture & Architecture: High-end furniture assembly and architectural fixtures where screw heads remain exposed.
  • Bicycles & Sporting Goods: Mounting accessories and structural components requiring high-strength fastening with minimal wind resistance.
