Description
Weatherproof Hex Head Self-Drilling Fasteners
Zinc Plated with EPDM Sealing Washer
Product Overview
These high-performance industrial fasteners feature a hexagonal washer head and specialized drill point, manufactured to DIN 7504K standard from Grade 410 stainless steel. Engineered to drill their own pilot hole, tap mating threads, and provide secure fastening in a single operation, these screws offer superior performance for metal-to-metal applications.
Core Features
  • Exceptional Hardness: Grade 410 stainless steel can be hardened through heat treatment, allowing 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
  • High Torque Strength: Hexagonal head design ensures maximum torque transmission and prevents cam-out during high-speed installation
  • Integrated Sealing: Compatible with EPDM bonded washers for leak-proof sealing in outdoor and roofing applications
