Product 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.

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.
