Product Description

DIN 7504K Stainless Steel 410 Self-Drilling Screws with Hex Washer Head

DIN 7504K self-drilling screws are high-performance industrial fasteners featuring a hexagonal washer head and specialized drill point. Manufactured from Grade 410 stainless steel, these screws drill their own pilot hole, tap mating threads, and provide secure fastening in a single operation. Grade 410 is a martensitic stainless steel that can be heat-treated, making it significantly harder than 304 or 316 grades for demanding metal-to-metal applications.

Core Features

Exceptional Hardness: Unlike 300-series stainless steel, 410 grade can be hardened through heat treatment, enabling penetration of carbon steel sheets and harder substrates without tip burnout.
Time-Saving Efficiency: Integrated drill point eliminates pre-drilling and hole alignment, 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 for outdoor and roofing applications.

Application Scenarios

Steel Construction & Metal Framing: Fastening metal sheets to steel purlins or sub-structures in industrial buildings.
Roofing & Cladding: Installation of metal roof panels and wall cladding systems requiring weather resistance and structural integrity.
HVAC Systems: Securing ductwork and mounting equipment components in heating and cooling systems.
Automotive & Machinery: Assembly line applications requiring high-speed fastening into metal frames.
Solar Energy Systems: Mounting solar panel brackets to aluminum or steel support rails.

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.
