Descrição do produto

High-Strength Zinc Coated Self-Drilling Screws with EPDM Washer

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

Core Features

Exceptional Hardness: Heat-treated 410 grade stainless steel penetrates 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: Reliable protection against atmospheric corrosion, water, and mild chemicals in humid environments
High Torque Strength: Hexagonal head design ensures maximum torque transmission and prevents cam-out during power tool installation
Integrated Sealing: EPDM bonded washers 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. Exact unit quantities per carton are confirmed with customers to align with specific requirements. Customized packaging configurations available upon request.

Outer Carton Box Packaging

Small cartons are consolidated into larger master cartons for secure transportation and storage. Quantity per master carton can be customized based on client specifications or standard logistical requirements.

Pallet Packaging

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.
