পণ্যের বর্ণনা
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.
