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.

Packaging Options
Carton Packaging
Bolts are packed in neutral packaging boxes, with standard quantities arranged in small cartons. The exact number of units per carton will be confirmed with the customer to align with their specific requirements. Customized packaging configurations are available upon request.
Outer Carton Box Packaging
The small cartons are then consolidated into larger master cartons for secure transportation and storage. The quantity per master carton can be customized based on client specifications or aligned with standard logistical requirements.
Pallet Packaging
The palletized units are securely wrapped with waterproof film and reinforced with packaging straps. Customer-specific shipping marks or labels are affixed to each pallet, ensuring clear identification and compliance with logistics requirements. This final packaging stage guarantees weather-resistant protection and stability during transportation.
